Amidrazones in the Synthesis of 1H-1,2,4-Triazoles

Abstract

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).
