  Generally applicable, palladium-catalyzed direct arylations of 1,2,3-triazoles with aryl chlorides were accomplished through conventional heating at reaction temperatures of 105–120 °C. Thereby, intra- and intermolecular CH bond functionalizations were achieved with a variety of differently substituted chlorides as electrophiles, bearing numerous valuable functional groups.

  通常适用的是，通过在105-120°C的反应温度下进行常规加热来实现1,2,3-三唑与芳基氯化物的钯催化直接芳基化。因此，用各种不同取代的氯化物作为亲电子体，实现了分子内和分子间的CH键官能化，并带有许多有价值的官能团。

  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‐disubstituted triazoles, which are readily accessible via "click" chemistry has been developed. It is important to note that CH bond functionalizations of 1,2,3‐triazoles with a variety of differently substituted aryl iodides and bromides as electrophiles

  An environmentally friendly and efficient method for synthesis of 1,4-disubstituted 5-iodo-1,2,3-triazoles through [Cu(phen)(PPh3)2]NO3-catalyzed cycloaddition of organic azides and iodoalkynes under solvent-free conditions was developed. Based on this, a one-pot method for the synthesis of fully substituted 1,2,3-triazoles via cycloaddition/Suzuki reactions was also demonstrated in this report.
