can readily be made from widely available or biomass-feedstock-derived carboxylic acids, their use as functional groups in metal-catalyzed cross-coupling reactions is rare. This report presents the first demonstration of Pd-catalyzed decarbonylative functionalization of acid fluorides to yield trifluoromethyl arenes (ArCF3 ). The strategy relies on a Pd/Xantphos catalytic system and the supply of fluoride
An effective model of cooperative effect of silver for the copper-catalyzedtrifluoromethylation of activated and unactivated aryliodides to trifluoromethylated arenes using Me3SiCF3 was achieved with a broad substrate scope.
