Kazaryan, S. Avakyan, é. Simonyan, A. Gevorkyan] 1-R-3-Methyl-2,3-epoxybutanes have been found to react with trifluoroacetic anhydride at 20-40‡C in the absence of a catalyst to give mixtures of the difluoroacetate and the product of substitutive O-acylation. The formation of the latter is favored by raising the temperature. The reaction mechanism is discussed. Plenum Publishing Corporation, 1990 Kazaryan P.
