A supporting electrolyte-free method for the electrochemical synthesis of trifluoromethylated oxindoles in conti- nuous flow was developed. Various N-arylacrylamides reacted with CF3SO2NHNHBoc smoothly to provide the corresponding products in moderate yields. The reaction scale-up was easily realized without changing the reaction conditions, which showed the application potential of continuous flow electrochemical synthesis.
