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.en5-нітро-NN-дифенілгідразинопіримидинивільні радикалиЕПР спектри5-нитро-NN-дифенилгидразинопиримидинысвободные радикалыЭПР спектры5-nitro-NN-diphenylhydrazinopyrimidinesfree radicalsESR spectraкафедра харчової хіміїArticle
