Abstract
Exchange reactions of trans-[PdXPh(SbPh 3) 2] (1) (X=Cl or Br) with ligands L in refluxing dichloromethane give the palladium phenyl complexes [PdXPhL 2] (X=Cl, L=PPh 3, AsPh 3, L 2=2,2′-bipyridine (bipy), 4,4′-dimethyl-2,2′-bipyridine (dmbipy), 1,10-phenanthroline (phen); X=Br, L=PPh 3, L 2=bipy). Treatment of the complexes with bis(diphenylphosphino)methane (dppm) in refluxing dichloromethane gives [PdXPh(dppm] 2. These complexes have been characterised by microanalysis, IR and 1H NMR spectroscopic data together with single crystal X-ray determinations of the phenyl palladium complexes, trans-[PdClPh(PPh 3) 2], [PdClPh(bipy)], [PdClPh(dppm)] 2, and [PdBrPh(dppm)] 2.
