    Summary:A new class of efficient catalyst, the Rh(I) complex [(eta(5)-C5Me5)Rh-I(bpy)] (1; bpy = 2,2'-bipyridine), for the C-F bond hydrogenolysis of fluoroaromatics (C6F5CF3, C6F6, C6F5H, and C6F5CH3) is presented. The best turnover number of 380 for C6F6 is afforded by using 0.1 mol % of 1, 0.8 MPa of H-2, and 2 equiv of Et2NH in CH3CN at 25 degrees C. The successful isolation of the C-F bond cleavage product [(eta(5)-C5Me5)Rh-III(bpy)(C6F5)](F) as a plausible intermediate of the catalytic hydrogenolysis of C6F6 by 1 is also described.

    Summary:Redox-active gold nanoparticles containing tetrathiafulvalene as an electron donor (TTF-Au nanoparticles) and fullerene C<SUB>60</SUB> as an electron acceptor (C<SUB>60</SUB>-Au nanoparticles) have been prepared by the reaction of octanethiol-stabilized gold nanoparticles with a tetrathiafulvalenyl-monothiol and a fullerene C<SUB>60</SUB>-terminated alkanethiol. Immersion of a gold electrode in a solution of the colloidal TTF-Au nanoparticles deposited the colloid films of them on the electrode surface, which were remarkably stable under repeated electrochemical cycling. Analogously, the self-assembly of C<SUB>60</SUB>-Au on planar gold surface led to the formation of the nanoparticle films which showed two distinct reversible reduction/oxidation waves and significant electrochemical stability. The electrochemical responses for the C<SUB>60</SUB>-Au nanoparticle films and self-assembled monolayers of the C<SUB>60</SUB>-thiol adsorbed on gold electrodes are significantly different. The nanocomposite films containing electron-donor and -acceptor functions such as TTF-Au and C<SUB>60</SUB>-Au can be characterized by cyclic voltammetry.

    Summary:Tetrathiafulvalenyl-thiol (1), disulfide (2), thioacetate (3), and sulfide (4) have been prepared. The redox behaviors of the tetrathiafulvalene derivatives (1-3) depended on the nature of an electrolyte and a solvent used. Though a difference of electrochemical behavior between 1 and 2 was found in the cyclic voltammograms, the self-assembled monolayers (SAMs) from 1 and 2 showed the similar redox behaviors, while, 4 did not form SAM on a gold (Au) electrode.

    Summary:The electrochemical property of alkane-tetrathiol or alkane-tetrapyrrole containing tetrathiafulvalene (TTF) and a new type of electropolymerization using the TTF-derivatized tetrathiol are described. Glassy carbon and gold electrodes have been modified by electropolymerization of the TTF-derived tetrathiol. The polymer films of the TTF-tetrathiol immobilized on glassy carbon and gold electrodes are remarkably stable to electrochemical recycling. The electrochemical behavior and the redox potentials of the polymer films of the TTF-tetrathiol depend on the nature of the counter anion of electrolyte or solvent. In contrast, the corresponding TTF-monothiol and TTF-tetrasulfide do not form the polymer films. The electrochemical property of the TTF-tetrathiol has been compared with that of the corresponding TTF-tetrapyrrole.

    Summary:The compounds that undergo photochromic reaction in the crystalline-state are rare and their reaction dynamics are not well characterized as a result of the low degree of interconversion ratios and/or instability of the photo-generated isomers in the solid phase. We have recently found that a rhodium Binuclear complex [ (RhCp<SUP>*</SUP>) <SUB>2</SUB> (μ-CH<SUB>2</SUB>) <SUB>2</SUB> (μ-O<SUB>2</SUB>SSO<SUB>2</SUB>) ] (Cp<SUP>*</SUP>=η<SUP>5</SUP>-C<SUB>5</SUB>Me<SUB>5</SUB>) having a photo-responsive dithionite group (μ-O<SUB>2</SUB>SSO<SUB>2</SUB>), undergoes an essentially 100% reversible crystalline-state photochromism upon interconversion to [ (RhCp<SUP>*</SUP>) <SUB>2</SUB> (μ-CH<SUB>2</SUB>) <SUB>2</SUB> (μ-O<SUB>2</SUB>SOSO) ] . Taking an advantage of this unique full reversibility, we have investigated the dynamics of the system by using stepwise single crystal diffraction and variable-temperature solid-state NMR technique. The stereospecifc oxygen-atom rearrangement process of the dithionite ligand and reorientational motion of the Cp<SUP>*</SUP> ligands, which are coupled to the photochromism, are presented.
  • Transformation of Inorganic Sulfurs Using Rhodium/Iridium Dinuclear Complexes, Isobe Kiyoshi, Nakai Hidetaka, Kojima Shota, Bull. Jpn. Soc. Coord. Chem., 50, 2, 17,   2007 , http://ci.nii.ac.jp/naid/130000141387
    Summary:In this article, we report unique reactivities of hydrogensulfide (SH), disulfide (S<sub>2</sub>), and oxydisulfide ligands (S<sub>2</sub>O<sub>n</sub>: n = 1-4) bridging between the Rh—Rh/Ir—Ir bonds. The hydrogensulfide and the disulfide ligand give rise to the S—C and C—C bond formation and the multi C—Cl bond activation, respectively. The oxydisulfide ligand (S<sub>2</sub>O<sub>4</sub>) shows a photoisomerization resulting in an intriguing crystalline-state photochromism. These reactivities are attributed mainly to the electron-rich Rh—Rh/Ir—Ir bond and the geometrical arrangement and the electronic character of the sulfide ligands.
