Amide derivatives of trifluoromethyl-substituted benzaldehydes, and their heterocyclic congeners, may be selectively cyclodefluorinated by a remote substitution reaction under mild conditions, giving difluoromethyl-substituted aldehydes after hydrolysis. Selective single and double defluorinations are possible using this method, which provides a versatile route to difluoromethyl arenes.
