Heinisch, G. published the artcileSynthesis and reactions of pyridazine derivatives. II. 4-Hydroxymethylpyridazine, Category: pyridazine, the publication is Monatsh. Chem. (1973), 104(5), 1354-9, database is CAplus.
4-(Hydroxymethyl)pyridazine (I) was obtained together with Et 2,5-dihydropyridazine-4-carboxylate by LiAlH4 or NaBH4 reduction of Et 4-pyridazinecarboxylate, the ratios depending on the reaction conditions. Reduction of 4-pyridazinecarboxaldehyde or 4-acetylpyridazine with NaBH4 gave I or 4-(1-hydroxyethyl)pyridazine, resp., in quant. yield. Treatment of I with SOCl2 gave 4-(chloromethyl)pyridazine.
Monatsh. Chem. published new progress about 50901-42-3. 50901-42-3 belongs to pyridazine, auxiliary class Pyridazine,Aldehyde, name is Pyridazine-4-carbaldehyde, and the molecular formula is C5H4N2O, Category: pyridazine.
