FeCl3 were employed as the chlorinating agent and catalyst respectively to convert benzyl esters into acid chloride intermediates, which directly reacted with alcohols, amines, and carboxylic acids. Various esters, amides, and anhydrides were readily obtained with high yields under mild conditions. This method is promising for the practical synthesis of esters, amides, and anhydrides from benzyl esters
描述了一种将苄酯轻松一锅转化为酯、酰胺和酸酐的方法。采用α,α-
二氯二苯甲烷和FeCl 3分别作为
氯化剂和催化剂,将苄酯转化为酰
氯中间体,直接与醇、胺、
羧酸反应。在温和的条件下很容易以高产率获得各种酯、酰胺和酸酐。该方法有望用于从苄酯实际合成酯、酰胺和酸酐。
