Facile acylation of alcohols using esters and silica gel-supported metallic sulphates and hydrogen sulphates
Abstract
Alcohols are acylated in a quite simple operation in high yields by being heated in esters in the presence of silica gel-supported metallic sulphates and hydrogen sulphates, such as Ce(SO4)2, Ti(SO4)2, Fe2(SO4)3, and NaHSO4.
