DMF-induced reaction of [(Z)-1-bromo-1-alkenyl]dialkylboranes with an N-halogeno compound results in 1,2migration of an alkyl group from the dialkylboryl group to the Ξ±-carbon atom without elimination of the bromine atom, followed by Ξ²-elimination to provide 1,2-disubstituted (E)-vinyl bromides ster
