Reaction of 5-substituted-2-methyl-3(2H)-pyridazinones with diarylnitrile imines generated in situ has been shown to afford diarylpyrazolo[3,4-d]pyridazin-4(5H)-ones. Structures of the products were proved by nmr spectroscopy. Reactivity and regiochemistry were analyzed by FMO theory. (C) 2000 Elsevier Science B.V.
