Reaction of 1-Methoxyimino-6-nitrohexa-2, 4-diene, Resulting from the Reaction of N-Methoxypyridinium Iodide with Nitromethane

Abstract

Chemical transformations of 1-methoxyimino-6-nitrohexa-2, 4-diene (II), resulted from the reaction of N-methoxypyridinium iodide (I) with nitromethane, were examined in relation to the nitro-aci-nitro prototropy. II reacted with diazomethane to afford methyl 1-methoxyimino-hexa-2, 4-diene-6-acinitronate (III), with acetic anhydride and with benzoyl chloride to give O-acetate and O-benzoate of 1-methoxyimino-hexa-2, 4-diene-6-hydroxamic acid (VI) respectively. The ultraviolet spectra of them were correlated to their structures.
