Synthesis of 4,4-substituted-5,5-mercapto-3,3'-bi-1,2,4-triazole and 2,2'-amino-substituted-5,5-bi-1,3,4-thiodiazole
In reaction of oxalic acid dihydrazide with isothiocyanates were obtained the respective thiosemicarbaside derivatives (Ia-IXa). Their cyclization in alkaline media have given the corresponding 4,4'-substituted-5,5'-mercapto-3,3'-bi-1,2,4-triazole (Ib-IXb
