The paper presents the results of the reduction of 4-nitroimidazoles, 4-nitropyrazoles and 3-nitropyridines by sodium borohydride or sodium borodeuteride in methanol in the presence of sodium methoxide, 1-Substituted 4-nitroimidazoles yield oximes of 4-imidazolidinones, the nitropyrazoles and nitropyridines yield respective azoxy compounds. The reaction mechanism proposed in the work makes allowances
本文介绍了在甲醇钠存在下在甲醇中用硼氢化钠或硼氢化氘化钠还原4-硝基咪唑,4-硝基吡唑和3-硝基吡啶的结果,1-取代的4-硝基咪唑生成4-咪唑啉酮的肟,硝基吡唑硝基吡啶和硝基吡啶分别产生氮杂化合物。在工作中提出的反应机理考虑了甲醇甲醇体系的催化作用。
