An efficient regioselective synthesis of 4-chalcogen-substituted arylamines by FeF3-catalyzed sulfenylation and selenation of arylamines has been developed. In the presence of FeF3 and I2, a variety of arylamines underwent the reaction with disulfides or diselenides to afford the corresponding 4-sulfenyl- or 4-selenenylarylamines in moderate to good yields.
