摘要：
A process for preparing fluorocarboxylic acid halides comprises the steps of (a) forming a starting composition comprising (i) at least one fluorosulfonic acid halide comprising at least one halosulfonyldifluoromethyl group (--Cf.sub.2 SO.sub.2 X, wherein X is halogen); and (ii) at least one Group III or Group V Lewis acid; and (b) allowing the fluorosulfonic acid halide and the Lewis acid to react to form a product composition comprising at least one fluorocarboxylic acid halide. The process enables the preparation of even higher molecular weight fluorocarboxylic acid halides in good yield.
