In this Communication, an investigation of the combination of N,N,N′,N′-tetramethylchloroformamidinium hexafluorophosphate (TCFH) and N-methylimidazole (NMI) for the synthesis of esters and thioesters is described. This work revealed the unique challenges of the reactions of less nucleophilic alcohols and more reactive thiols with the N-acyl imidazolium intermediate and led to the identification of
在本通讯中,描述了N , N , N ', N '-四甲基氯甲脒六氟磷酸盐 (TCFH) 和N-甲基咪唑 (NMI) 组合用于合成酯和硫酯的研究。这项工作揭示了亲核性较低的醇和反应性较高的硫醇与N-酰基咪唑鎓中间体反应的独特挑战,并确定了为一系列醇和硫醇提供高产率和选择性的一般有利条件。
