Synthesis of 4,4'-dinitro-1H,1'H-[3,3'-bipyrazole]-5,5'-diamine
摘要:
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-1H, 1'H-[3,3'-bipyrazole]-5,5'-diamine and its nitration was studied.

General methods have been worked out for the alkylation of nitroazoles with bromoacetone, bromoacetophenone, and diazoacetone in homogeneous media and by phase-transfer catalysis. The structures of the N-acetonylazoles were established by C-13, N-15, and N-14 high-resolution NMR spectroscopy.
