      The catalytic transfer hydrogenation of carbonyl compounds allows easy synthesis of alcohols under mild conditions. This review describes recent achievements in the preparation of a novel class of highly efficient Rucatalysts based on the 1-(pyridin-2-yl)methanamine motif. Asymmetric reduction of ketones occurs fast and with unprecedented productivity.

      The derivatives [Pt2(μ-PtBu2)2(L)(L′)] (L, L′ = PR3, PR2H, CO) were treated with CF3SO3H to investigate ligand effects on the site of protonation. When at least one of the terminal ligands is a basic phosphane, protonation at Pt and formation of [Pt2(μ-PtBu2)2(H)(L)(L′)](CF3SO3) is always observed, whereas [Pt(μ-PtBu2)(CO)]2 is protonated at the phosphorus atom of a bridging phosphide.

    6. Luminescent Ru Complexes

      The electrochemical and photophysical properties of a range of Ru(II) tris-2,2′-bipyridine complexes in which a thiophene substituent is attached to one of the bpy ligands via either a pendant or a fused mode have been determined. The electrochemical properties of these complexes were found to be similar; however, the luminescence lifetimes and intensities were found to be correlated to the mode of attachment.

      Rigid bifunctional meta-phosphonobenzoic acid 2 was used to synthesize hybrid materials. Lamellar materials I2O1 are obtained with Mn2+ and Co2+ salts possessingthe formula M(H2O)(m-O3PC6H5CO2H). The reaction of 2 with Zn2+ salts gave either a lamellar material or a 3D structure depending of the pH of the reaction media.

      Yttrium(III) chloride complexes [YCl2(NNOR)] were synthesized. Reaction of [YCl2(NNOH)] with MeMgBr led to the formation of the MgII derivative [Mg2BrCl{NN(Me)OH}(thf)]2. Reaction of theneutral ligand NNOH-H with Y(CH2SiMe3)3·2thf afforded the alkyl complex[Y(CH2SiMe3){NN(CH2SiMe3)O}(thf)],and the reaction mechanism was simulated by using the PM6 Hamiltonian.

      Dinuclear copper(II) complexes of two N-methylated bis(tacn) ligands, Lmemx and Lmeox, are reported in which auxiliary acetato ligands adopt chelating and bridging coordination modes, respectively, due to the differing constraints imposed by thebis(tacn) ligands. The aqua derivative of the former complex is an effective model phosphate diester cleavage agent.
