Potassium carbonate: a highly efficient catalyst for the acylation of alcohols, phenols and thiols under mild conditions
Volume 2, Issue 1, pp. 1-81, Serial No. 2 , January 2014, Pages 39-47
Abstract
A general, mild and efficient protocol has been developed for the synthesis of esters and thioesters. The process has been taking place using tetra n-butylammonium iodide (TBAI) as a phase-transfer catalyst and in the presence of potassium carbonate (K2CO3). A wide range of esters and thioesters was ... Read More)
