A NOVEL SYNTHESIS OF DIFLUOROMETHYL KETONES FROM 2,2,2-TRIFLUOROMETHYL p-TOLUENESULFONATE VIA 2,2-DIFLUOROALKENYLBORANES
Ichikawa, Junji,Sonoda, Takaaki,Kobayashi, Hiroshi
, p. 5437 - 5438 (2007/10/02)
Oxidation of 2,2-difluoroalkenylboranes can be achived with alkaline hydrogen peroxide in the presence of sodium methoxide, which suppresses protonolysis, to afford difluoromethyl ketones in good yields.
