Abstract An efficient regioselective synthesis of 4-chalcogen-substituted arylamines by FeF 3- catalyzed sulfenylation and selenation of arylamines has been developed. In the presence of FeF 3 and I 2, 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.
