the development of green and sustainable methods for direct C−H bond arylation of (hetero)arenes. In this context, here the infrared (IR) irradiation-assisted solvent-free Pd-catalyzed direct C−H bond arylation of (hetero)arenes was achieved. Several heteroaryl-aryl coupling reactions were described, also involving heterocycles commonly used as building blocks for the synthesis of organic semiconductors

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
