Unsubstituted 1H,7H-dipyrazolo[3,4-b;4′,3′-e]pyrazine has been synthesized for the first time starting from 5-amino-3-methyl-1-phenylpyrazole. Its nitration to formC- andN-dinitro-substituted derivatives has been studied. The molecular structure of 3,5-dinitro-1H,7H-dipyrazolo[3,4-b;4',3t′-e]pyrazine has been established by X-ray structural investigation; the NH acidity of this compound and the orientation of its alkylation with bromoacetone have also been determined.
