Article abstract of DOI:10.1016/0040-4039(92)80023-D

2,2,2-Trifluoroethyl p-toluenesulfonate is treated with butyllithium and trialkylboranes successively to generate 1-alkyl-2,2-difluorovinylboranes, which couple with aryl iodides in the presence of cuprous iodide and palladium catalyst to afford 1,1-difluoro-1-alkenes in excellent yields. Key Words: Difluoroalkene; Difluorovinylborane; Transmetalation; Coupling reaction; Palladium catalyst
