The reactions of N-methoxypyridinium iodide with nitromethane, nitroethane, and 1-nitropropane in the presence of sodium ethoxide in anhydrous ethanol afforded 1-methoxyimino-6-nitrohexa-2,4-diene, 1-methoxyimino-6-aci-nitrohepta-2,4-diene, and 1-methoxyimini-6-aci-nitroocta-2,4-diene, respectively. The spectral behaviors of these products were discussed in relation to the nitro-acinitro prototropy and the assumed reaction mechanism was also offered.
