1-Alkenyldibromoboranes readily obtainable by the hydroboration of first alkyneswith dibromoborane-dimethyl sulfide followed by treatment with tribromoborane, react without any difficulty with second 1-alkynes as bromoborating agents to give (l-alkenyl)(Z-bromo-l-alkeny)bromoboranes (5). The reactio
