Abstract
The corresponding hydrazones, azo compounds, and 2,4-bis(1H-pyrazol-1-yl)pyrimidines were synthesized by the reaction of 5-ethyl-2-hydrazino-6-methyl-4(3H)-pyrimidinone, 2-(N-p-butylanilino)-4-hydrazino-6-methylpyrimidine, and 4-hydrazino-2-(1H-pyrazol-1-yl)pyrimidines with salicylaldehyde, isatin, β-naphthoquinone, phenanthrenequinone, and acetylacetone. The structures of the synthesized compounds are discussed on the basis of a study of their electronic, IR, and mass spectra.
