    Summary:In imidazolium ILs, the negative charge delocalization induced by multiple electron-withdrawing cyano groups can be useful in regulating the microscopic environment in imidazolium ILs. For this anion design, the ion-counterion (solvent-solvent) interaction is weakened, the ion-solute (solvent-solute) interaction is facilitated, and the bulkiness of the anion is increased. The electrostatic interaction with the cation has a strong effect on the ion states of the ILs and the stereoselectivity in the Diels-Alder reaction. These regulation methods potentially have wide applications to various useful reactions using ILs. © 2013 The Royal Society of Chemistry.

    Summary:We directly observe the interaction between 1-butyl-3-methylimidazolium ( bmim) or 1-butyl-2,3-dimethylimidazolium (bm(2)im) and the solute, ethyl acrylate ( EA), which is the popular dienophile in the Diels-Alder reaction and an H-bonding acceptor, by using specially designed electrospray mass spectrometry. In imidazolium ionic liquids, cation-anion interactions are controlled by selecting the appropriate anion, and the naked C-2-H of imidazolium, which loosely interacts with its counterion, can readily interact with an H-bonding acceptable solute. The ion-counterion (solvent-solvent) interaction affects the ion-solute (solvent-solute) interaction. This relation is one of the key criteria for selecting the cation-anion combination in tailoring ILs.

    Summary:Water-insoluble pyridinium-based ionic liquids with a disulfide bond were prepared. Reduction of these ionic liquids using sodium hydrosulfite changed the water solubilities of the ionic liquids because the structural exchange of disulfide into thiol groups increases their polarities. Such a structural change by oxidationreduction enables reversible control of the phase separation property of ionic liquids with water.
  • First Observation for Dynamic Solvent Effect in Ionic Liquids, Satoshi Kitaoka, Kaoru Nobuoka, Junji Miura, Yasushi Ohga, Yuichi Ishikawa, CHEMISTRY LETTERS, CHEMISTRY LETTERS, 45(4), 385 - 387, Apr. 2016 , Refereed
    Summary:We observed pressure effects on the rate of thermal fading of colored chromene 1 photochemically generated from 2 in ionic liquids. The reaction rates were retarded with increasing pressure in [C-4-mim][CS], [bzl-mint][Tf2N], and [mnp-mim][Tf2N], whereas the reaction rate increased with pressures in [C-4-mim][Tf2N]. These pressure-induced retardations, so-called dynamic solvent effects, result from the slow thermal fluctuations of solvents.

    Summary:We examined photoresponsive ionic liquids containing an azobenzene moiety. Ionic liquids with a p,p'-azobenzene or o,p'-tetrafluoroazobenzene moiety exhibit a reversible solid-to-liquid phase transition induced by photo- and thermal-stimulation. o,p'-Azobenzene, which exists as an ionic liquid with a bent structure, is in a liquid state even as a trans-isomer. Such photoresponsive ionic liquids may be useful as novel functional materials, such as in optical sensors.
  • A simple method for efficient synthesis of tetrapyridyl-porphyrin using Adler method in acidic ionic liquids, Satoshi Kitaoka, Kaoru Nobuoka, Keita Ihara, Yuichi Ishikawa, RSC ADVANCES, RSC ADVANCES, 4(51), 26777 - 26782, 2014 , Refereed
    Summary:We investigated the preparation of tetraphenylporphyrin (TPP) using the several acidic ionic liquids, [HC(4)im] [X] (X- = CF3SO3-, ClO4-, Cl-, CF3CO2-, and BF4-), as acid catalytic media. For such ionic liquids, the anion (X-) of [HC(4)im][X] is related to the acidity of the ionic liquid, and affects porphyrin formation. This synthetic method using acidic ionic liquids can also be applied to other meso-substituted phenyl porphyrins and 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine (TPyP), which has 4-pyridyl moieties at four meso positions. In [HC(4)im][CF3CO2], TPyP could be obtained in 11% yield, and the [HC(4)im][CF3CO2] could be reused at least 3 times without any loss of its catalytic activity. The TPyP synthesis methodology using acidic ionic liquids can remove the ionic liquids from TPyP by easy filtration in contrast to the traditional Alder method, which needs vacuum distillation or liquid-liquid extraction for removing propionic acid. Our proposed porphyrin preparation method using the acidic ionic liquids potentially have wide applications to various useful porphyrin analogues.

    Summary:We report the preparation of tetraphenylporphyrin (TPP) in acidic ionic liquids. In [HC4im][CF3CO2] and [HC 4im][BF4], TPP could be obtained in 15% and 9% yields, respectively. The yield in [HC4im][CF3CO2] was the same as that for the reaction in propionic acid (15%). In addition, [HC 4im][CF3CO2] could be reused at least 3 times without any loss of its catalytic activity. Use of acidic ionic liquids for porphyrin synthesis can afford the porphyrins without producing any acid waste. © 2013 The Chemical Society of Japan.
  • Preparation and Properties of Low Viscous Triazolate-based Ionic Liquids Containing Two Cyano Groups, Satoshi Kitaoka, Kaoru Nobuoka, Naoki Yoshiiwa, Thomas Harran, Yuichi Ishikawa, CHEMISTRY LETTERS, CHEMISTRY LETTERS, 39(11), 1142 - 1143, Nov. 2010 , Refereed
    Summary:We synthesized novel triazolate-based ionic liquids containing two cyano groups. These liquids exhibit lower viscosity and glass transition temperatures than the ionic liquids without cyano groups. The present method of delocalizing anion charges in triazolate-based ionic liquids by means of cyano substitutions may be applicable to other ionic liquids to reduce their viscosity, thus making them promising reactive media and electrolytes.
  • Porphyrin preparation utilizing sulfonated ionic liquid and control of cation-anion interaction in ionic liquids, Satoshi Kitaoka, Kaoru Nobuoka, Yuichi Ishikawa, Yuki Gosei Kagaku Kyokaishi/Journal of Synthetic Organic Chemistry, Yuki Gosei Kagaku Kyokaishi/Journal of Synthetic Organic Chemistry, 67(8), 833 - 842, 2009 , Refereed
    Summary:We have studied the development of functionalized ionic liquids and control of cation-anion interaction in ionic liquids. Herein we report that utilizing a functionalized ionic liquid with a sulfonate group enable us to carry out greener porphyrin syntheses than ever. Such an ionic liquid shows an effective reactivity and a green property by working as an acidic catalyst which is separated from the reaction medium. Moreover, the specific solvation behaviour in ionic liquids was investigated in order to effectively apply the ionic liquids for various reactions. We have found out that [C4mim] [CS] composed of a bulky camphorsulfonate as an anion provides a ionic liquid. The ES-MS analyses of it revealed a loose interaction between the C 4mim+ and the bulky CS-. The [C4mim] [CS] produced an effective endo/exo stereoselectivity in the Diels-Alder reaction. The loose cation-anion interaction of [C4mim] [CS] produces a more naked C4mim+. Therefore the naked C 4mim+ can more readily contact the reactant further than its counter-anion. The ES-MS analysis directly demonstrated these interactions.
  • Cluster Structure of Imidazolium Salts in Methanol Controlled by the Balance of Interactions: Cation-Anion, Cation-Solvent, and Anion-Solvent, Satoshi Kitaoka, Kaoru Nobuoka, Yuichi Ishikawa, Akihiro Wakisaka, ANALYTICAL SCIENCES, ANALYTICAL SCIENCES, 24(10), 1311 - 1314, Oct. 2008 , Refereed
    Summary:We have studied the cluster structure of 1-butyl-3-methylimidazolium halide, bmimX (X = Cl, Br, I), in methanol solution by means of an electrospray mass spectrometer, which is specially designed for analysis of clusters isolated from solution. In positive ion mode experiments, the ratio of solvated bmim(+), bmim(+)(MeOH)(n), and ion-pair clusters, bmim(bmim(+)X(-))(m) was dependent on the counter anion. As for bmimCl solutions, few solvated bmim(+) clusters were observed, and the ion-pair clusters were clearly observed. On the other hand, bmimBr and bmiml with large anions, the solvated bmim(+) clusters increased obviously, and the ion-pair clusters were in turn remarkably decreased. In negative ion-mode experiments, the solvation for Br- by the methanol is found to be the most prominent among those for Cl-, Br-, and I-. These results were reasonably explained in consideration of the balance between ion-solvent and ion-counterion interactions.
  • Camphor ionic liquid: Correlation between stereoselectivity and cation-anion interaction, K Nobuoka, S Kitaoka, K Kunimitsu, M Iio, T Harran, A Wakisaka, Y Ishikawa, JOURNAL OF ORGANIC CHEMISTRY, JOURNAL OF ORGANIC CHEMISTRY, 70(24), 10106 - 10108, Nov. 2005 , Refereed
    Summary:As a halogen-free anion for an imidazolium room temperature ionic liquid, the use of a camphorsulfonate causes an increase in the number of free (naked) imidazolium cations, which produces an effective endolexo stereoselective DielsAlder reaction.
  • Ionic liquids for tetraarylporphyrin preparation, S Kitaoka, K Nobuoka, Y Ishikawa, TETRAHEDRON, TETRAHEDRON, 61(32), 7678 - 7685, Aug. 2005 , Refereed
    Summary:In place of widely used dichloromethane, a series of ionic liquids, ILs, was employed as a reaction medium for the one-flask preparation of tetraarylporphyrins. The porphyrin yield in the IL was comparable to that in the dichloromethane, as long as both the water content and the fluidity were conditioned to be in the optimum state. When acidic IL,[C-4-SAbim][CF3SO3] possessing a sulfonic acid moiety was used as the reaction medium, nothing but a black tarry by-product was obtained due to its strong acidity. However, using the acidic IL in a biphasic mode together with dichloromethane, enabled porphyrins to form, even at a high reactant concentration. Furthermore, the phase-separated acidic IL was reusable for at least 10 times without any loss of catalytic activity. (c) 2005 Elsevier Ltd. All rights reserved.
  • The first utilization of acidic ionic liquid for preparation of tetraarylporphyrins, S Kitaoka, K Nobuoka, Y Ishikawa, CHEMICAL COMMUNICATIONS, CHEMICAL COMMUNICATIONS, 10(17), 1902 - 1903, 2004 , Refereed
    Summary:A phase-separated acidic ionic liquid affords to catalyze a reaction of pyrrole with benzaldehyde in dichloromethane, forming porphyrins in a comparable yield to the Lindsey method and is reusable at least ten times without loss of catalytic activity.

    Summary:We synthesized the novel chiral ionic liquid based on L-proline which is an excellent chiral catalyst for various asymmetric reactions. The proline type ionic liquid showed very low melting point and viscosity, and an effective catalytic activity for asymmetric Michael addition reactions of cyclohexanone to nitrostyrenes to afford the corresponding Michael adducts in high yields (up to 96 %), diastereoselectivities (syn/anti ratio up to 96/4), and enantioselectivities (up to 95 % ee). The proline type chiral ionic liquid could be easily recovered and the recovered ionic liquid could be reused for at least three times without significant loss of diastereoselectivities and enantioselectivities. We report the synthesis and properties of the proline type chiral ionic liquid and several asymmetric reactions catalyzed by the ionic liquid.
  • Effect of Anion Structures of Ionic Liquids on Thermal Cyclization of Chromene Derivatives, MIURA JUNJI, KITAOKA SATOSHI, NOBUOKA KAORU, OHGA YASUSHI, ISHIKAWA YUICHI, Abstracts of Symposium on Physical Organic Chemistry,   2009
    Summary:The pressure effect on the rate of thermal fading of open form chromene photochemically generated from close form chromene was measured in multiple ionic liquids. The activation volumes of the thermal cyclezation of chromene were equivalent in almost ionic liquids. Exceptionally, the activation volume was negatively small only in [bmim][CS]. It seemed the desolvation around chromene was promoted, because CS anion was too bulky. To prove the desolvation from the chromene in [bmim][CS], the dilution effect of [bmim][CS] by [bmim][TFSI] was investigated.

    Summary:In recent years, ionic liquids have received a considerable upsurge of interest as electrolytes for various electrochemical devices, such as Li-ion batteries, dye-sensitized solar cells. This is mainly attributable to their superior properties, such as non-flammability, non-volatility and intrinsic ion conductivity. High ionic conductivity and fast ion mobility (including the doped ions such as Li+ for Li batteries) are the requirements for ionic liquids as supporting electrolytes in high-energy devices. This means that the viscosity of ionic liquids must be as low as possible. Therefore, we synthesized multiple low-viscosity ionic liquids. We report the viscosity, ion conductivity and the melting point of these ionic liquids.

    Summary:In the Diels-Alder reaction using imidazolium ionic liquids with charge delocalized anions, high stereoselectivity is shown. These ionic liquids show weaker anion- cation interaction. This situation allows hydrogen bonding between the C2 hydrogen of the imidazolium and the carbonyl oxygen of the dienophile and act like a Lewis acid catalyst. In this study, we report that the effect of ionic liquid with charge delocalized anion as a Diels-Alder reation media in various conditions and Lewis acid catalyst in various reactions.

    Summary:In general, rearrangement of solvent molecules is more rapid than movement of a reactant solute. However, this relation can be inverted when viscosity of the used solvent drastically increase by applying high pressure. Here we firstly report this phenomenon, known as the dynamic solvent effect, could be observable even in imidazolium ionic liquids. Pressure effect (0.1 M-600 Mpa) on a photoisomerization reaction in an ionic liquid was monitored from the viewpoint of the molecular structure of the salt medium. We would discuss the relation between the dynamic solvent effect and the salt design (side chain structure of the imidazolium cation and anion size).

    Summary:[Abstract] We investigated the substituent effects on the viscosity of azole based ionic liquids. Introducing some electro withdrawing groups to the azole anion and some electron donating groups to the azole cation decreased the viscosity of ionic liquids. In these substituent effects to azole anion and azole cation, the anion and cation charge are delocalized over substituent groups. The decrease in the anion and cation charge density weakens the cation-anion interaction of ionic liquids. As a result, the viscosity of ionic liquids becomes lower. The present method of delocalizing anion and cation charges in azole-based ionic liquids by means of substitutions may be applicable to other ionic liquids to reduce their viscosity, thus making them promising reactive media and electrolytes.
