Trifluoromethyl benzoate (TFBz) is developed as a new shelf-stable trifluoromethoxylation reagent, which can be easily prepared from inexpensive starting materials using KF as the only fluorine source. The synthetic potency of TFBz is demonstrated by trifluoromethoxylation-halogenation of arynes, nucleophilic substitution of alkyl (pseudo)halides, cross-coupling with aryl stannanes, and asymmetric

A hydrofluoroether compound comprises two terminal, independently fluoroalkyl or perfluoroalkyl groups and an intervening oxytetrafluoroethylidene moiety (—OCF(CF
3
)—) bonded through its central carbon atom to an alkoxy- or fluoroalkoxy-substituted fluoromethylene moiety (—CF(OR)—), each of the terminal groups optionally comprising at least one catenated heteroatom.

The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy carboxylic acid or ester, e.g., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.2 COOH. The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water-wettable and dyeable.
