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(0) CATALYST IN OLIGOMERIZATION OF METHYLENECYCLOPROPANE

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.

Metallacycloalkanes, VI. Five- to Seven-membered (2,2'-Bipyridine)nickelacycloalkanes from Methylenecyclopropane and Nickel(0) Compounds

Depending on the reaction conditions (2,2'-bipyridine)(η2-methylenecyclopropane)nickel (4) or the (2,2'-bipyridine)nickelacycloalkanes 5 - 8 were obtained from methylenecyclopropane (1) and (2,2'-bipyridine)(1,5-cyclooctadiene)nickel.The complexes were characterized spectroscopically and by decomposition reactions. 5 - 8 react with methyl acrylate under reductive elimination to give the cycloalkanes 2 (from 5), 3 (from 6a, b), or 9 (from 7).With CO 5 reacts additionally through an insertion to yield the cyclopentanone derivative 10.Alcoholysis of 5 with ethanol affords 2-cyclopropylmethyl-1-butene (11), whereas with phenol the new (2,2'-bipyridine)nickel complex 12 was formed.
