N-Heterocyclic carbene catalyzed esterification of aromatic aldehydes with alcohols under aerobic conditions†
Abstract
A simple, organocatalytic procedure for the direct oxidative esterification of a variety of aromatic aldehydes with alcohols has been described that affords the corresponding aromatic esters in high yields. The method employs N-heterocyclic carbenes as catalysts and molecular O2 as an oxidant under ambient conditions.
