1‐Alkyl‐4,5‐dichloropyridazin‐6‐oncs 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.
