Chemical and electrochemical reductions of some allyl type halides catalyzed by vitamin B-12

Abstract

Chemical and electrochemical reductions of some allyl type halides catalyzed by vitamin B-12 have been studied. Geranyl bromide 1 and methyl (2E, 6E) 8-bromo-3,7-dimethylocta-2,6-dienoate 2 have been used as substrates and subjected to chemical and electrochemical reduction. The formation and distribution of the reaction products of these substrates can be explained by free radical mechanisms, namely by reductive reactions of some functional groups, rearrangements and intermolecular coupling of intermediate radicals.
