  Acrylonitrile Polymerization by Cy₃PCuMe and (Bipy)₂FeEt₂

  摘要：

  Cy3PCuMe (1) undergoes reversible ligand redistribution at low temperature in solution to form the tight ion pair [Cu(PCy3)(2)][CuMe2] (3). The structure of 3 was assigned on the basis of (i) the stoichiometry of the 1 = 3 equilibrium, (ii) the observation of a triplet for the PCy3 C1 C-13 NMR resonance due to virtual coupling to two P-31 nuclei, and (iii) reverse synthesis of 1 by combining separately generated Cu(PCy3)(2)(+) and CuMe2- ions. Complex 1 and [Cu(PCy3)(2)][PF6] (5) coordinate additional PCy3 to form (Cy3P)(2)CuMe and [Cu(PCy3)(3)][PF6], respectively, while 3 does not. Complex 1, free PCy3, and (bipy)(2)FeEt2 (2) each initiate the polymerization of acrylonitrile. In each case, the polyacrylonitrile contains branches that are characteristic of an anionic polymerization mechanism. The major initiator in acrylonitrile polymerization by 1 is PCy3, which is liberated from 1. A transient iron hydride complex is proposed to initiate acrylonitrile polymerization by 2.

• Thermal decomposition of methylcopper and methyl(tricyclohexylphosphine)copper

  The thermal decomposition of CH3Cu and CH3CuPCy3 has been studied in the solid state and in solution. Ligand-free methylcopper and its complex with tricyclohexylphosphine gave on thermolysis methane, ethane, ethylene and propane as gaseous products. The solvent does not affect the composition of the gases, and when carried out in benzene-d6 the thermolysis does not yield deuterated gases. Thermal decomposition

  已经研究了固态和溶液中CH 3 Cu和CH 3 CuPCy 3的热分解。无配体的甲基铜及其与三环己基膦的配合物以热解的形式产生气态产物甲烷，乙烷，乙烯和丙烷。溶剂不会影响气体的组成，并且在苯-d 6中进行时，热分解不会产生氘代气体。CD 3 CuPCy 3的热分解产生摩尔比为3：2的CD 3 H和CD 4，表明用于形成甲烷的氢的来源是三环己基膦（60％）和CD 3的甲基铜（40％）。铜-碳σ键断裂是通过双分子协同反应中的还原消除进行的。
