O-Benzoylated cyanohydrins of aromatic aldehydes have been used as one of the substrates in the benzoin condensation.They were treated with aromatic aldehydes under phase-transfer conditions to result in benzoin benzoates.By this method aldehydes which fail to undergo condensation using traditional conditions could be converted into benzoins.By the Umpolung of reactivity of the pertinent aldehyde it was possible to prepare both isomeric unsymmetrical benzoins, including the thermodynamically less stable ones.
