Abstract

Tetrakis (dimethylamino) ethylene (TDAE) was found to be an effective reductant of chlorodifluoromethylated ketones1–3. The generated α, α-difluoroacetyl anion was trapped with several aldehydes4–7, under mild conditions, to give the corresponding 2, 2-difluoro-3- hydroxy ketone derivatives8–13, in moderate yields.
