Pd-catalyzed regioselective C-H chlorination of disubstituted 1,2,3-triazoles
This paper mainly studied Pd-catalyzed regioselective chlorination of disubstituted 1,2,3-triazoles directed by the 1,2,3-triazole ring. A series of regioselective chlorinated products were synthesized in 47–86% yields using Pd(OAc)2 as a catalyst and ...

Interrupted Click Reaction with CuCF2CF3 Reagent: Synthesis of 5‑Pentafluoroethyl 1,2,3-Triazoles
We herein describe a three-component interrupted click reaction to synthesize novel 5-pentafluoroethyl 1,2,3-triazoles in one step from readily available terminal alkynes and azides.

Strategies Towards the Synthesis of N2-Substituted 1,2,3-Triazoles
The chemistry of 1,2,3-triazoles gained much attention since the discovery of the copper catalyzed Alkyne-azide cycloaddition (CuAAC) reaction which delivers exclusively the 1,4-regioisomer in high yields.
