The paper presents the results of the reduction of 4-nitroimidazoles, 4-nitropyrazoles and 3-nitropyridines by sodiumborohydride 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
The treatment of 4-nitroimidazoles with an excess of sodium borohydride in the presence of sodium methoxide yields the (Z)-oximes of 4-imidazolidinones. The title compound, 1-phenyl-4-imidazolidinone (Z)-oxime, C9H11N3O, is a coplanar molecule despite the saturation of the hetero ring.
