Copper-catalyzed remote oxidation of alcohols initiated by radical difluoroalkylation of alkenes: facile access to difluoroalkylated carbonyl compounds.

A Cu-catalyzed oxidation of alcohols triggered by the radical difluoroalkylation of alkenes has been developed, providing facile access to a series of difluoroalkylated ketones or aldehydes in moderate to high yields. The concurrent realization of the catalytic oxidation of alcohols and difluoroalkylation of alkenes enables a highly efficient and attractive method for organic synthesis.
