Alkylcuprates react with 1-bromo-1,2-dienes to give allenic and/or acetylenic products. The selectivity of the crosscoupling is markedly dependent on the nature of the copper reagent, which plays a prominent role in determining both the regio- and the stereo-chemistry. The preparative aspects of these copper-induced reactions are discussed and their possible mechanism discussed.
