醇与酸酐的酰化反应是一种温和而有效的制备多种酯的方法，该反应在多种金属三氟甲磺酸盐的催化下进行。机理的见解表明，三氟甲磺酸是在这些反应条件下产生的，并且至少有两个竞争性的催化循环同时进行：一个快速的涉及三氟甲磺酸和一个较慢的涉及金属三氟甲磺酸盐。(C)2003爱思唯尔有限公司。保留所有权利。
The acylation of alcohols by anhydrides, catalysed by a wide range of metal triflates, is a powerful and mild method for the preparation of a variety of esters. Mechanistic insights demonstrate that triflic acid is generated under these reaction conditions and that, at least, two competing catalytic cycles are operating at the same time: a rapid one involving triflic acid and a slower one involving the metal triflate.
