Abstract

The synthesis and catalytic activity of triazolopyridinylidene as a novel abnormal N-heterocyclic carbene (aNHC) ligand was described. The evaluation of physical properties using X-ray crystallographic analysis and infrared spectroscopy revealed that these triazolopyridinyli-denes have a high electron-donating ability to the metal center. Aapplication of triazolopyridinylidenes to palladium-catalyzed cross-coupling of chloroarenes and nitroarenes showcased its ability to activate C–Cl and C–NO2 bonds.
