NHC-catalyzed generation of difluorocarbene from trimethylsilyl 2,2-difluoro-2-(fluorosulfonyl)acetate (TFDA) enables the synthesis of enol difluoromethyl ethers starting from cyclohexenones and tetralones. The resultant enol difluoromethyl ethers were successively dehydrogenated with DDQ to furnish aryl difluoromethyl ethers in good to high yield.
