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.
通过 FeF3 催化芳胺的亚砜化和亚
硒化,开发出了一种高效的区域选择性合成 4-
钙原取代的芳胺的方法。在 FeF3 和 I2 的存在下,各种芳胺与二
