Catalytic properties of several supported Pd(II) complexes for Suzuki coupling reactions

Abstract Pd(II) complexes with N-ligands were synthesized and tested for Suzuki coupling reaction. These complexes were also heterogenized on silica. The resulting site-isolated catalysts showed a high catalytic activity. The most stable complex was supported N -(propyl)ethylenediamine, which did not display any notable leaching. The effects of reaction conditions and the nature of the boronic acid derivative on the conversion of the starting compounds were studied.
