Abstract

Abstract Organocuprates induce 1, 3-and direct substitution in 3-alkyl-and 3, 3-dialkyl-1- bromo-1, 2-dienes leading respectively to either terminal acetylenes or allenic hydrocarbons. The nature of the cuprate exerts a prominent role in determining both the regio-and the stereochemistry of these reactions.
