  Catalytic conversions of cyclic C3-olefins in the presence of metal complexes. 6. Effect of P(NEt2)3 ligand on the properties of complex Ni(O) catalyst in oligomerization of methylenecyclopropane

  摘要：

  Preferential formation of di- or trimers of methylenecyclopropane (MCP) under the influence of Ni(O) complexes is determined by the nature of ligands, additions of modifiers, and the reaction conditions. The Ni(O) complex with coordinated P(NEt2)3 was synthesized via a proposed intermediate catalytic system Ni(COD)2-P(NEt2)3 by the interaction between Ni(eta-3-C3H5)2 and P(NEt2)3. The composition of the complex: {Ni[P(NEt2)3]2}x (K-1) was established by H-1 and P-31{H-1} NMR, EPR spectroscopy, IR diffuse reflectance spectroscopy, and GLC. In the range 20-60-degrees-C complex K-1 only brings about trimerization of MCP. The catalytic properties of K-1 were described earlier by a proposed scheme for the catalytic conversion of MCP under the influence of Ni(O) complexes.
