title: I2/TBPB mediated oxidative reaction of N-tosylhydrazones with anilines: practical construction of 1,4-disubstituted 1,2,3-triazoles under metal-free and azide-free conditions.
abstract: An efficient I2 (20 mol %)/TBPB mediated oxidative formal [4 + 1] cycloaddition of N-tosylhydrazones with anilines via C-N/N-N bond formation and S-N cleavage has been developed. This protocol represents a simple, general, and efficient approach for the construction of 1,2,3-triazoles under metal-free and azide-free conditions by utilizing a catalytic amount of I2.
