The '''transacylation''' of [[ester]]s involves the reaction of an ester (typically an acetate ester) with a [[carboxylic acid]] to produce a new ester, along with a new carboxylic acid (typically [[acetic acid]]).  We discovered that this process can occur in high yield with [[acetate]] esters, in the presence of hydrated [[dysprosium(III) triflate]], as long as the process is driven by removal of the product acid ([[acetic acid]]).  For example, p-tolyl acetate reacts with p-anisic acid to produce a new ester, p-tolyl p-anisate, and acetic acid:
