Reactions with excess hydrazine hydrate of 5-nitropyridin-2(1H)-ones fused with benzene, pyridine, and 1,2,3-triazole rings led to a cyclotransformation of the 5-nitro-2-oxopyridine fragment into the 6-methyl-3-oxopyridazine structure. This cyclotransformation is of general character; a probable mechanism of the process is suggested. Details of the assumed mechanism were experimentally confirmed on model compounds.
与过量的肼水合物反应的5-硝基吡啶-2(1H)-酮与苯、吡啶和1,2,3-三嗪环的熔合,导致了5-硝基-2-氧基吡啶片段向6-甲基-3-氧基吡唑啉结构的环转化。该环转化具有一般特征;提出了该过程的可能机制。对假定机制的细节在模型化合物上进行了实验确认。
