An eco-friendly and effective electrochemical process was developed for the ortho-trifluoromethylation of arylamines using CF3SO2Na as the trifluoromethyl source, affording the desired products in moderate to good yields with high regioselectivity under mild reaction conditions. Importantly, the requirement for both transition metals and oxidants utilized in previous methods were avoided. A radical mechanism was proposed on the basis of various control experiments.
