An addition/elimination reaction of organolithium reagents to silylated beta,beta-difluorostyrene derivatives followed by a bromination/desilicobromination reaction provides a simple and effective synthetic approach to a wide range of bromofluoroalkenes (up to >97/3). In addition, the bromofluoroalkenes can be used in Pd-catalyzed transformations giving access to both tri- and tetrasubstituted fluoroalkenes.
