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.
