An efficient N-heterocyclic carbene-catalyzed oxidative esterification reaction of aldehydes with ethyl bromoacetate or bromoacetonitrile has been explored. This transition metal-free protocol allows access to a wide variety of α-acyloxyacetates and cyanomethyl esters in good to excellent yields under mild reaction condition.

Key words: carbene, aldehydes, esterification, oxidation, organocatalysis
