A NOVEL SYNTHESIS OF DIFLUOROMETHYL KETONES FROM 2,2,2-TRIFLUOROMETHYL p-TOLUENESULFONATE VIA 2,2-DIFLUOROALKENYLBORANES
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.
