Summary: Dialkylboranes, generated in situ via hydridation of dialkylhaloboranes, hydroborate l-bromo-l-alkpes to provide cleanly B-(cis-1-bromo-1-alkeny1) dialkyl-boranes. Treatment of these intermediates with sodium methoxide results in the migration of one of the alkyl groups on boron to the adjacent carbon, displacing the bromine, providing B-(trans- 1-alkyl-1-alkenyl) alkyl-
