reactive diazo compounds and then into extremely reactive carbenes under the basic condition. In order to fulfil the valuable C‐N coupling reaction, diaryliodonium salts are evaluated and prove to be a class of efficient electrophiles. The reaction with ligand‐free copper salt as catalyst shows a wide range of substrate scope. A plausible mechanism is proposed.
甲苯磺酰hydr是一种不稳定的高反应性化合物,在碱性条件下易于转化为反应性重氮化合物,然后再转化为高度反应性的卡宾。为了完成有价值的C-N偶联反应,对二芳基
