Substitution reactions of trans-[PdXPh(SbPh3)2J (X=Cl or Br) with nitrogen, phosphines and arsenic donor ligands. Crystal structures of trans-[PdClPh(PPh3)2], [PdClPh(bipy)], [PdClPh(dppm)]2, and [PdBrPh(dppm)]2
摘要:
Exchange reactions of trans-[PdXPh(SbPh3)(2)] (1) (X = Cl or Br) with ligands L in refluxing dichloromethane give the palladium phenyl complexes [PdXPhL2] (X = Cl, L = PPh3, AsPh3, L-2 = 2,2'-bipyridine (bipy), 4,4'-dimethyl-2,2'-bipyridine (dmbipy), 1,10-phenanthroline (phen); X = Br, L = PPh3, 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 H-1 NMR spectroscopic data together with single crystal X-ray determinations of the phenyl palladium complexes, trans-[PdClPh(PPh3)(2)], [PdClPh(bipy)], [pdClPh(dppm)](2), and [PdBrPh(dppm)](2).
