Phenyl(6-phenyl-pyridazin-3-yl)methanol (3) has been obtained via NaBH4 reduction of ketone 2. Reaction of 2 with hydroxylamine or its O-alkyl analogue has been found to yield 3-benzoyloxime-6-phenylpyridazine (4) and alkyloximes (5), respectively. Treatment of 4 with a mixture of aceticacid and sulfuric acid afforded ketone 2 again and not the rearranged products (6 or 7). Beckmannrearrangement has however been
