Novel Heterocyclization of Hydrazinopyridazinones with Dimethyl Acetylenedicarboxylate with Dehydrogenation and Rearrangement

5-Hydrazinopyridazin-3(2H)-ones 1 reacted with dimethyl acetylenedicarboxylate 2 to give 4,6-dihydropyridazinopyridazin-5-(1H)-ones 3 by cyclization with dehydrogenation.On the other hand, the reaction of 4-bromo-5-hydrazino- and 5-bromo-4-hydrazin
