dimethyl acetal (DMFDMA) by heating or by microwave irradiation. Compound was treated with active methylene nitriles followed by hydrazine hydrate derivatives to give bisaminopyrazole derivatives. Other bisazoles can be obtained by reacting with aminoazole derivatives. Cyclization of Bis [2-(p-phenelyeneimino)malononitrile] to 1,10-diaminophenanthroline-2,9-dicarbonitrile is also reported. J.
