Документ Synthesis of 5-nitro-N,N-diphenylhydrazinopyrimidines and investigation of their free radicals(1980) Boldyrev, I. V.; Polumbryk, Oleg; Markovskii, Leonid; Cherkasov, V. M.A number of 5-nitro-N,N-diphenylhydrazinopyrimidines were synthesized. Free radicals were obtaines by oxidation of these compounds with PbO2. The stabilities of 5-nitro-4-pyrimidinylhydrazyl radicals are close to the stability of the α,α-diphenyl--2,4-dinitrophenylhydrazyl radical. The structures of the compounds obtained were confirmed by the UV, IR, PMR and EPR spectra.
