A highly practical and general base‐catalyzed carbonylation of amines to the corresponding N‐formamides has been realized. Cheap inorganic bases, including Group IA and IIA metal hydroxides, alkoxides, carbonates, and phosphates, were effective catalysts for the transformation. In the presence of 10–40 mol % of KOH or K2CO3, various amines were converted into the corresponding N‐formamides in good‐to‐excellent
已经实现了一种高度实用且通用的碱催化的胺羰基化为相应的N-甲酰胺的方法。廉价的无机碱,包括IA和IIA组金属氢氧化物,醇盐,碳酸盐和磷酸盐,是转化的有效催化剂。在存在10–40 mol%的KOH或K 2 CO 3的情况下,使用CO作为甲酰化试剂,可以将各种胺以良好或优异的产率转化为相应的N-甲酰胺。
