An efficient Cu-catalyzed strategy for the direct C–Hamination of arenes in high yields using N-hydroxyphthalimide as the amidyl radical precursor under air is reported. A possible mechanism is proposed that proceeds via a radical reaction in the presence of CuBr and triethyl phosphite.
报道了一种使用N-羟基邻苯二甲酰亚胺作为酰胺基自由基前体在空气下以高产率直接 C-H 胺化芳烃的有效 Cu 催化策略。提出了一种可能的机制,即在 CuBr 和亚磷酸三乙酯存在下通过自由基反应进行。
