Synthesis and Catalytic Activity of Ionic Palladium N-Heterocyclic Carbene Complexes

Abstract

The synthesis of 3 benzimidazole-based ionic Pd(II)-NHC complexes (NHC: N -heterocyclic carbene) is presented. The structures of the complexes are as follows: [NHC-PdBr <inf>3</inf> ] − [NHC] + . The ionic palladium(II)-NHC complexes were synthesized in high yields and were fully characterized by nuclear magnetic resonance spectroscopy, X-ray diffraction, LC-MS/MS, and elemental analysis. These complexes have been identified as active catalysts in Suzuki–Miyaura reactions in a solution of 2-propanol and water at room temperature for different aryl bromides. © TÜBİTAK.
