摘要

The acylation of alcohols and phenols to esters with carboxylic anhydrides is a fundamental chemical transformation in the production of important intermediates and fine chemicals.[1] 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.[2–8] Lewis acids such as Sc (OTf) 3,[4] Me3SiOTf,[5] and In (OTf) 3 [6] have ...
