Facile Synthesis of 2-Aryl-3-phenyl-5-phenylamino-2,5-dihydro-1,2,4-thiadiazole-5-carbonitriles
摘要:
Syntheses of various 2-aryl-3-phenyl-5-phenylamino-2,5-dihydro-1,2,4-thiadia- zole-5-carbonitriles are reported. The key to their successful synthesis is represented by the reaction of N-imidoylthioureas with 2-(1,3-dioxoindan-2-ylidene)malononitrile.
