A novel synthetic approach toward 1,4‐disubstituted 1,2,3‐triazoles by CN‐ and NN‐bond formation has been established under transition‐metal‐free conditions. Complete control of the regioselectivity was successfully achieved. Commercially available anilines, ketones, and N‐tosylhydrazine were treated with molecular iodine in one pot to allow the regioselective generation of 1,4‐disubstituted 1,2
A green, general and efficient I2/TBHP mediated syntheticmethodtoward 1,4-disubstituted 1,2,3-triazoles via the reactions of acetophenones, tosylhydrazine and anilines within 35 min in a two-step continuous flow system has been developed. The reaction proceeds smoothly to afford 1,4-disubstituted 1,2,3-triazoles in moderate to good yield under metal- and azide-free conditions by using I2 as a catalyst
