The present invention provides a method of acylating organic amines using N,N'-diacylimidazolone derivatives represented by the general formula I as follows: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different, which are selected from the group consisting of methyl, ethyl, straight or substituted aliphatic chain of C.sub.3 -C.sub.19, phenyl, heterocyclic groups, alkoxy and other organic acid substituting groups; and R.sub.3 and R.sub.4 are the same or different, which are selected from the group consisting hydrogen, methyl or ethyl, phenyl, substituted phenyl and alkoxycarbonyl, or wherein R.sub.3 and R.sub.4 form a R-substituted benzene ring having the following structure together with a carbon atom where R.sub.3 and R.sub.4 are bonded to: ##STR2## (wherein R is hydrogen, carboxyl or sulfonic groups).
本发明提供了一种使用N,N'-二酰亚咪唑酮衍生物的方法,该衍生物由以下一般式I表示:##STR1## 其中R.sub.1和R.sub.2相同或不同,选自甲基、乙基、直链或C.sub.3-C.sub.19的取代脂肪链、苯基、杂环基、烷氧基和其他有机酸取代基的群;R.sub.3和R.sub.4相同或不同,选自氢、甲基或乙基、苯基、取代苯基和烷氧羰基的群,或者其中R.sub.3和R.sub.4与它们连接的碳原子一起形成以下结构的R-取代苯环:##STR2## (其中R是氢、羧基或磺酸基)。
