2-Fluorocarbonyl- and 2-fluorosulfonylpentafluoropropenes upon cooling add allyl and propargyl alcohols at the C = C bond to form strong CH-Acids (I) - (IV). These CH-acids react with BF3.NEt3 under mild conditions and are converted to 2-fluorocarbonyl- and 2-fluorosulfonyl-2-trifluoromethyl-substituted unsaturated acid fluorides (V) - (VIII). The conditions, rate, and high selectivity of these reactions support the hypothesis that the formation of acid fluorides (V) - (VIII) involves a [3,3]-sigmatropic rearrangement of intermediate carbanions (Ia) - (IVa).
