Preparation of 1-methyl-2,2-diphenylcyclopropylcobaloxime and theoretical considerations for its mode of formation

Abstract

The title compound, which contains a stable tertiary alkylcobalt σ-bond, is readily obtained from the reaction of pyridine[bis(dimethylglyoximato)]cobalt(I) and 1-methyl-2,2-diphenylcyclopyl bromide; five mechanisms for the reactions of low-valent metal ions and alkyl halides are discussed.
