A metal‐free aerobicoxidativeesterification of aldehydes in the presence of cyanide is described. Various aromatic aldehydes and sterically congested alcohols were amenable to this protocol. In addition, this method could be extended to the preparation of thioesters with a thiol in place of an alcohol. Furthermore, the cyanide‐mediated aerobicoxidation of aldehydes was applied to the synthesis of
