The syntheses of various 2-(4-aryl-2,4-dihydro-3-phenyl-1,2,4-triazol-3-ylidene)indan-1,3-diones are reported. The key to their successful synthesis depends on the reaction of amidrazones 1a - f with 2-(1,3-dioxoindan-2-ylidene)malononitrile (2).
Various (2 Z)-2-(( E)[arylamino]phenylmethylene}hydrazono)-1,4-diphenylbutan-1,4-diones are obtained during the reaction of amidrazones with 1,4-diphenylbut-2-yne-1,4-dione (DBD) in boiling ethanol.
