Tetrakis (dimethylamino) ethylene (TDAE) as a useful reductant of some chlorodifluoromethylated ketones. A new approach for the synthesis of α, α-difluoroketone …
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.
