An I2O5-promoted decarboxylative trifluoromethylation of a series of cinnamic acids and their derivatives by using sodium trifluoromethanesulfinate in aqueous media was demonstrated. This strategy provides a safe and convenient access to various trifluoromethylated (E)-alkenes in a very high selectivity.

A copper-catalyzed decarboxylative trifluoromethylation of various α,β-unsaturated carboxylic acids by using a stable and inexpensive solid, sodium trifluoromethanesulfinate (CF3SO2Na, Langlois reagent), was developed. In addition, an iron-catalyzed difluoromethylation of aryl-substituted acrylic acids by using zinc difluoromethanesulfinate (DFMS, (CF2HSO2)2Zn, Baran reagent) via a similar radical process was also achieved.

Dual action: The Lewis acid CuF2·2 H2O efficiently catalyzes the reaction between electrophilic fluoroalkylating agents and α,β-unsaturated carboxylic acids by dually activating both reactants, thus affording di- and trifluoromethyl alkenes in high yields with excellent E/Z selectivity. Copyright
