  ane)]2 were also determined. We report a systematic, solvent-dependent method to prepare palladium(II) complexes of the aryl phosphines o-methylphenyldiphenylphosphane, o-cyclohexylphenyldiphenylphosphane and o-phenylphenyldiphenylphosphane with a desired nuclearity. We demonstrated that chlorinated solvents promote the formation of dinuclear chlorine-bridged palladium complexes for all five ligands

  AbstractMono‐ and dinuclear palladium(II) chloride complexes of various ortho‐alkyl‐substituted aryl‐ and alkylphosphanes were prepared. Subsequently, these were characterized by 1H NMR and 31P1H} NMR spectroscopy, X‐ray crystallographic studies and mass spectroscopy. The palladium complexes were screened as potential catalysts for the microwave‐assisted Suzuki–Miyaura coupling reaction of several aryl halides under aerobic conditions. A preliminary study showed that excellent results can be obtained even for electron‐rich bromides and unactivated aryl chlorides with an optimized solvent, base and catalyst loading using specific phosphane ligands.
