Contrary to previous reports, the reaction of anilines and phenylglyoxal in toluene affords the expected anil PhCO-CH=N-Ar, 1.In many cases it is more convenient to carry out the reaction in methanol where the methanol adduct of 1 forms, which may be better isolated, characterised and stored.Since the alcohol adduct is in equilibrium with free 1, it can be used for synthetic purposes as precursor of 1 as in hydrolysis, Diels-Alder, and other reactions initiated by nucleophilic attack on the carbon-nitrogen double bond.

Amination of α,α-diaminoketones I by 4,5-dimethyl-o-phenylenediamine gave 6,7-dimethyl-2-phenylquinoxaline (II) in a high yield.The reaction may occur through formation of α-ketoazomethine III.The α,α-diaminoketones were obtained by condensation of phenyl
