J. Suwinski et al., REDUCTION OF AROMATIC NITROCOMPOUNDS BY SODIUM-BOROHYDRIDE IN METHANOL IN THE PRESENCE OF SODIUM METHOXIDE, Tetrahedron, 52(28), 1996, pp. 9541-9552
The paper presents the results of the reduction of 1-nitroimidazoles,
4-nitropyrasoles and 3-nitropyridines by sodium borohydride or sodium
borodeuteride in methanol in the presence of sodium methoside. 1-subst
ituted 4-nitroimidazoles yield oximes of 4-imidazolidinones, the nitro
pyrazoles and nitropyridines yield respective azoxy compounds. The rea
ction mechanism proposed in the work makes allowances for catalytic ef
fect of the system methanol-methoxide. Copyright (C) 1996 Elsevier Sci
