Article abstract of DOI:10.1246/bcsj.57.544

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.
