Condensed Imidazo-1,2,4-triazines. 7. Reaction of 2-Hydrazinobenz(naphth)imidazoles with Acetylacetone

Article abstract of DOI:10.1007/BF00512821

Hetaryl analogs of biphenyl, viz., 2-(3',5'-dimethyl-1'-pyrazolyl)benz(naphth)imidazoles, were obtained instead of the expected benz(naphth)imidazo-1,2,4-triazepines in the condensation of 2-hydrazinobenz(naphth)imidazoles with acetylacetone.The structure of the final products was established on the basis of the PMR and mass spectra and by the data from the x-ray diffraction analysis.
