Abstract

An electro-oxidative strategy enables an efficient decarboxylative trifluoromethylation of α,β-unsaturated carboxylic acids using the Langlois reagent as a trifluoromethyl precursor. Under catalyst-free and external oxidant-free conditions, a series of trifluoromethylated styrenes are obtained with a high regioselectivity in good yields.
