A copper-catalyzed decarboxylative trifluoromethylation of various alpha,beta-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)(2)Zn, Baran reagent) via a similar radical process was also achieved.
