- Concurrent Alkylation-Methoxylation of 4,5-Dihalopyridazin-6-ones and Synthesis of 5-Halo-4-hydroxypyridazin-6-ones
-
1-Alkyl-5-halo-4-methoxypyridazin-6-ones were synthesized from 1-alkyl-4,5-dihalopyridazin-6-ones by the concurrent alkylation-methoxylation. 1-Alkyl-5-halo-4-hydroxypyridazin-6-ones were also prepared.

- Retro-ene reaction. II. Reaction of 4,5-dichloro-1-hydroxymethylpyridazin-6-one with alkyl halides and carboxylic acid chlorides
-
1-Alkyl-4,5-dichloropyridazin-6-ones and (4,5-dichloro-6-oxopyridazin-1-yl)methylcarboxylates were synthesized from 4,5-dichloro-1-hydroxymethylpyridazin-6-one and the corresponding alkyl halides or carboxylic acid chlorides. Also the reaction mechanisms via a fragmentation of retro-ene type are discussed.
