Cp(2)Sm(thf)(2) was found to be an efficient catalyst for the acylation of alcohols and amines with esters under mild conditions. In the present acylation, vinyl and isopropenyl acetates served as good acylating agents. Thus, a variety of alcohols and amines underwent acylation with vinyl and isopropenyl acetates in the presence of Cp(2)Sm(thf)(2) to give the corresponding esters and amides in good
发现Cp(2)Sm(thf)(2)是在温和条件下用酯酰化醇类和胺类的有效催化剂。在本发明的酰化中,乙酸乙烯基酯和异丙烯基乙酸酯用作良好的酰化剂。因此,在Cp(2)Sm(thf)(2)存在下,各种醇和胺与乙酸乙烯基酯和异丙烯基乙酸酯进行酰化反应,以良好或极好的收率得到相应的酯和酰胺。醇和胺的这种催化酰化通过在非常温和的条件下使用各种酯代替酸酐和酰氯作为酰化剂,提供了另一种有用的方法。
