trimerization of aldehydes in the presence of cyanide via metal-freeaerobicoxidativeesterification under ambient conditions is described. Various aromatic aldehydes provided the corresponding oxidativeesterification products in good to excellent yields. Mechanistic studies suggested that this reaction would proceed via a two-step sequence: cyanide-catalyzed benzoin condensation of aldehydes and subsequent
