The higher propensity of C-N over C-S bond forming ability was demonstrated, through formal C-H functionalization during the construction of 4,5-disubstituted 1,2,4-triazole-3-thiones from arylidenearylthiosemicarbazides catalyzed by Cu(II). However, ster

3,4-Diaryl-4H-1,2,4-triazoles were obtained in good to comparable yields by the reaction of N-alkyl-N-phenylsulfonyl-N''-arylbenzamidrazones with sodium hydride.The reaction probably proceeds via the elimination of benzenesulfinic acid and the oxidative cyclization of N-alkylidene-N''-arylbenzamidrazones generated by the base-catalyzed isomerization of azo intermediates.
