sulfones employing trifluoromethyl α-fluorinated arylsulfonyl gem-diols and aryl aldehydes under mild reaction conditions has been developed, which affords α-fluorinated arylvinyl sulfones in high yields with E-isomer only. The desired products can be further transformed into more useful fluoroolefins through debenzenesulfonyl process.
