We report a C–N cross-coupling reaction of weakly nucleophilic N-arylsulfonamides and aryl bromides to access N,N-diarylsulfonamides using Ni(cod)(DQ) as a catalyst without additional ligands. The process is compatible with electron-deficient and electron-rich aryl and heteroaryl bromides (34 examples, 21–98%) and can be applied to the derivatization of an N-arylsulfonamide pharmaceutical compound
我们报告了弱亲核性N-芳基磺酰胺和芳基溴化物的 C-N 交叉偶联反应,使用 Ni(cod)(DQ) 作为催化剂,无需额外的配体即可获得N , N-二芳基磺酰胺。该工艺与缺电子和富电子的芳基和杂芳基溴化物兼容(34 个例子,21-98%),可用于N-芳基磺酰胺药物化合物的衍生化。
