Electrochemical Decarboxylative Trifluoromethylation of α, β‐Unsaturated Carboxylic Acids with CF3SO2Na.

A new method for the synthesis of vinyl trifluoromethyl compounds from α, β‐unsaturated carboxylic acids and CF3SO2Na has been developed. This electrochemical decarboxylative trifluoro‐methylation was found to be highly stereoselective and afforded products in good yields with wide substrate scope under metal‐free and external chemical oxidant‐free conditions.
