Abstract

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 for catalytic effect of the system methanol-methoxide.
