one‐pot synthesis of N‐(hetero)aryl carbamates through the reaction between alcohols and in‐situ produced (hetero)aryl isocyanates in the presence of a nickel catalyst. The phenolic C−O bond was activated via the reaction of phenol with cyanuric chloride (2,4,6‐trichloro‐1,3,5‐triazine (TCT)) as an inexpensive and readily available reagent. This strategy provides practical access to N‐(hetero)aryl carbamates
设计了一种简单有效的多米诺反应,并通过在镍催化剂存在下,醇与原位生成的(杂)芳基异氰酸酯之间的反应,单锅合成N-(杂)芳基氨基甲酸酯。通过苯酚与氰尿酰氯(2,4,6-三氯-1,3,5-三嗪(TCT))反应可以活化酚C-O键,这是一种廉价且易于获得的试剂。该策略提供了以高收率和高官能团相容性实际获得N-(杂)芳基氨基甲酸酯的方法。
