A Highly Selective,High-Speed,and Hydrolysis-Free O-Acylation in Subcritical Water in the Absence of a Catalyst

摘要

The acylation of alcohols and phenols to esters with carbox-ylic anhydrides is a fundamental chemical transformation in the production of important intermediates and fine chemicals.Catalytic versions of this reaction are being investigated intensively to replace the current non-stoichiometric acylation processes that generate large amounts of carboxylic acid and solvent waste.
