Preferential formation of di- or trimers of methylenecyclopropane (MCP) under influence of Ni(0) complexes is determined by the nature of ligands, additions of modifiers, and the reaction conditions.The Ni(0) 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(η3-C3H5)2 and P(NEt2)3.The composition of the complex: 2>x (K-1) was established by 1H and 31P- NMR, EPR spectroscopy, IR diffuse reflectance spectroscopy, and GLC.In the range 20-60 deg 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(0) complexes.
