A copper-catalyzed decarboxylative cycloaddition of propiolic acids, azides, and arylboronicacids is described. The present reaction provides an efficient and convenient method for the synthesis of various fully substituted 1,2,3-triazoles from readily available starting materials. A possible mechanism is proposed.

highly efficient method for the synthesis of unsymmetrical multi‐substituted 1,2,3‐triazoles via a direct Pd‐NHC system catalyzed C(5)‐arylation of 1,4‐disubstitutedtriazoles, which are readily accessible via "click" chemistry has been developed. It is important to note that CH bond functionalizations of 1,2,3‐triazoles with a variety of differently substituted aryl iodides and bromides as electrophiles

An environmentally friendly and efficient synthesis of fully substituted 1,2,3-triazoles comprises solvent-free palladium-catalyzed Suzuki cross-coupling of halo-1,2,3-triazoles with pinacol arylboronates. The efficiencies of Stine and Suzuki reactions with halotriazoles under solvent-free conditions were compared.
