Two novel N-heterocyclic carbene-palladium(II) complexes were conveniently synthesized through one-pot reactions of imidazolium salts, palladium chloride and acridine. The new complexes have been fully characterized by H-1 NMR, C-13 NMR, elemental analysis, and X-ray single-crystal diffraction. Moreover, the obtained palladium(II) complexes were the effective catalyst precursors for the Suzuki-Miyaura coupling of aryl as well as benzyl chlorides with arylboronic acids. Under the optimal conditions, all reactions proceeded successfully to give the desired products in good to almost quantitative yields.
