Abstract

Abstract The coordination mode in a metal complex is critically dependent on the ligands surrounding the metal, on the precursors used, and on the conditions during synthesis. Our goal was to obtain palladium compounds with pyridine-phosphane ligands for catalysis. Therefore, we synthesized ligands 1a–d, which differ in the bulky aryl substituent at the pyridyl moiety. The palladium complexes 6a–d of these ligands are insoluble and have ...
