An efficient synthesis of novel 3’-substituted 2-aryl-5-methyl-5'thioxo-[4,4'-bi-4H-1,2,4-triazol]-3(1'H, 2H)-ones

Abstract

Asimple and high yieldingmethod for the integration of two 1,2,4-triazole rings (10a–l) has been developed starting from 3-arylsydnones (1a–d). Confirmation for the structures of the newly synthesised compounds was provided by their physical, analytical and spectral data (IR, 1H NMR, 13C NMR and MS).
