Abstract
Abstract 2,2,2-Trifluoroethyl p-toluenesulfonate is treated with butyllithium and trialkylboranes successively to generate 1-alkyl-2,2-difluorovinylboranes, which in turn react with acyl chlorides or chloroformates in the presence of cuprous iodide to afford 2,2-difluorovinyl carbonyl compounds in good yields.
