Pyridazines. V. The Reaction of Methyl Substituted 4-Nitropyridazine 1-Oxides with Acetyl Chloride

Reaction of excess acetyl chloride on a 3-substituted 4-nitro-6-methylpyridazine 1-oxide (Ia, b, c and XIII) result in the formation of 3-substituted 4-chloro-6-formylpyridazine 1-oxide oximes (IIa, b, c and XVIII), together with 3-substituted 4-chloro-6-methylpyridazine 1-oxides (IIa, b, c and XVII...

Zusammenfassung:Reaction of excess acetyl chloride on a 3-substituted 4-nitro-6-methylpyridazine 1-oxide (Ia, b, c and XIII) result in the formation of 3-substituted 4-chloro-6-formylpyridazine 1-oxide oximes (IIa, b, c and XVIII), together with 3-substituted 4-chloro-6-methylpyridazine 1-oxides (IIa, b, c and XVII). Reaction of 3-methyl-4-nitropyridazine 1-oxide (XII) and 4-nitro-5-methylpyridazine 1-oxide (XIV) with acetyl chloride gave only 3-methyl-4-chloropyridazine 1-oxide (XIII) and 4-chloro-5-methylpyridazine 1-oxide (XV) respectively.
