    WCl(η2-C2Ph2)(η6-C6Ph6H):  A Compound Containing a Metallacycloheptatriene Unit from Trimerization of Diphenylacetylene with W(NMe3)(η2-C2Ph2)3
    摘要:
    W(NCMe)(eta(2)-C2Ph2)(3) (1) has been previously synthesized by the reaction of W(CO)(eta(2)-C2Ph2)3 Wit Me3NO in acetonitrile, while the same treatment in THF leads to the trimethylamine complex W(NMe3)(eta(2)-C2Ph2)(3) (2). Compound 2 is reactive. Stirring a mixture of 2 and diphenylacetylene in dichloromethane at room temperature affords WCl(eta(2)-C2Ph2)(eta(6)-C6Ph6H) (3), which apparently arises from trimerization of the alkyne ligands concomitant with solvent activation. The structures of 1-3 have been determined by an X-ray diffraction study. A carbene W=C double bond is evidenced in 3.

    摘要:
    The 1,3,5-trimethyl-1,3,5-triazacyclohexane (Me(3)tach) group in [M(CO)(3)(Me(3)tach)] complexes (M=Mo, W) is easily displaced by a variety of ligands under mild conditions. The lability of the Me(3)tach ligand allows the [M(CO)(3)(Me(3)tach)] complexes to be used as synthetic intermediates in convenient syntheses of products such as fac-[M(CO)(3)(CH3CN)(3)] (M=Mo,W), [W(CO)(alkyne)(3)], [W(CO)(3)(PR3)(2)] and [W(CO)(3)(eta(6)-arene)] complexes. An improved synthesis of [W(CO)(3)(Me(3)tach)] from [W(CO)(6)] and Me(3)tach is described. (C) 1998 Elsevier Science S.A. All rights reserved.

    η-alkyne complexes [W(CO)(RCCR)3] (R  Ph, SMe) react with the ditertiary alkylphosphine Me2PCH2CH2PMe2 (dmpe) in dichloromethane solution at ambient temperature. [W(CO)(MeSCCSMe)3] produces [W(CO)-(dmpe)(MeSCCSMe)2] and eventually [W(dmpe)(MeSCCSMe)2]; with excess dmpe, [W2(dmpe)5(MeSCCSMe)] is formed. All of the alkyne ligands are rapidly displaced from [W(CO)(PhCCPh)3] to give cis-[W(CO)2(dmpe)2]
