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