  Nickel complexes are found to be catalytically active in the cross-coupling reactions of allenic bromides with alkyl metals to give substituted allenes in excellent yields. The catalytic process proceeds generally with inversion of configuration in the allenyl moiety.

  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.

  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.
