    Different reaction behaviour of molybdenum and tungsten – Reactions of the dichloro dioxo dimethyl-bispyridine complexes with thiophenolate
    摘要:
    The reaction of the metal complexes MO2Cl2(mebipy) (M = Mo, W) with two equivalents thiophenol by the exact same procedure leads to two different products for molybdenum [Mo2O4(SPh)(2)(mebipy)(2)] and tungsten [WO2(SPh)2(mebipy)]. To understand why this is the case the redox potentials of the starting materials were measured showing that the redox potential for thiophenol is lower than the redox potentials (M-v <-> M-vi) for both of the metal precursors. A reduction of the metal and oxidation of the sulfur should be possible for both reactions but occurs only for the molybdenum compound. Theoretical calculations show that different metal-sulfur bond strengths are as well and equally responsible for the differing reaction behaviour as are the redox potentials. (C) 2007 Elsevier B.V.

    Reaction of these proligands HLn (n = 1–5) with [WO2Cl2(DME)] (DME = 1,2-dimethoxyethane) in the presence of triethylamine leads to the formation of cis-dioxotungsten(VI) complexes [WO2(Ln)Cl] (n = 1–5). Treatment of the chloro derivatives [WO2(Ln)Cl] (n = 1, 5) with the Grignard reagents RMgX (R = CH2SiMe3, C6H4tBu-4; X = Cl, Br) resulted in ligand substitution reaction and the formation of the first

    catalyst in the sulfoxidation of methyl phenyl sulfide and in the epoxidation of cis -cyclooctene with tert -butylhydroperoxide, under mild conditions. The BINOL complex was, however, not found to be enantioselective. In addition, the catalytic activity of the molybdenum species MoO 2 ( S -BINOL)(THF) 2 and MoO 2 [OCMe(CF 3 ) 2 ] 2 (THF) in the hydrosilylation of carbonyl groups has been explored.
