Arylazo derivatives of imidazothiazoles, imidazopyrazoles, imidazo-s-triazoles, imidazopyrimidines, and imidazopyridines were obtained in good yields from α-keto hydrazidoyl halides and 2-aminothiazole, 5-aminopyrazole, 5-aminotriazole, 2-aminopyrimidine, and 2-aminopyridine, respectively (cf.Tables I and II).The structures of the products were assigned and confirmed on the basis of their elemental analyses, spectra, and alternate synthesis wherever possible.

The behaviour of several amino- and hydroxy-diazoles towards nitrile imines and hydrazonoyl halides is reported.The results indicate that nitrile imines can add to the double bonds in amino- and hydroxy-heterocyclic derivatives.However, the nature of the
