Abstract

Herein, we describe a nickel-catalyzed reductive difluoromethylation reaction of alkene using inexpensive and easy-to-handle DFAA/pyridine N-oxide reagent system. A variety of C(sp3)-CF2H containing compounds were prepared through a hydrodifluoromethylation process with good efficiency under mild conditions. In addition, various gem-difluoroalkenes bearing CF2H or 1o, 2o, 3o alkyl group were synthesized from trifluoromethyl alkenes via a defluorination process using this new established approach.
