SYNTHESIS OF 4,4'-DINITRO-1H,1'H-[3,3'-BIPYRAZOLE]-5,5'-DIAMINE

Abstract
All of the synthetically accessible symmetric tetranitro-3,3'-bipyrazoles were prepared. On their basis, a method was developed for the synthesis of 4,4'-dinitro-1Н,1'Н-[3,3'-bipyrazole]-5,5'-diamine and its nitration was studied.
Keywords
bipyrazole, diaminodinitrobipyrazole, tetranitrobipyrazole, cine-substitution, nitration, nucleophilic substitution.
