1,1-Bis(dimethylamino)-2,2,2-trifluoroethane is an excellent synthetic building-block replacement for trifluoroacetaldehyde in condensation reactions with ketones using 36% aqueous HCl catalysis. Moderate to good yields (43–68%) of trifluoromethyl carbinols are obtained with symmetric and unsymmetric methyl ketones, with the latter undergoing reaction mainly at the methyl group. Its reactions with
