Investigation of complexes of diphenylphosphine derivatives by thermal and other physicochemical methods of analyses
Zayed,Arifien,Hassan
, p. 205 - 212 (1999)
Six heteroatomic complexes of diphenylphosphine derivatives with heavy metals (Ni, Pd, Pt, Mo and W) were prepared and subjected to elemental spectral and thermal analyses. The different physicochemical methods used indicated the formulae [NiCl2(dppm)], [PtCl2(dppm)] and [Mo(CO)4(dppm)] (dppm = bis(diphenylphosphine)methane, the dppm in these complexes behaving as a bidentate ligand), [Pd(CN)2(dppm)2] (in which the dppm behaves as a monodentate ligand), [W(CO)4(dppe)2] and [Mo(CO)4(dppe)2] (dppe = 1,1-bis(diphenylphosphine)ethene, the dppe in these complexes behaving as a bidentate ligand). The thermal analyses (DTA and TG) confirmed these structures. The results of spectral and thermal analyses were compared.

Treatment of Cl2, i.e. Cl2, with NaCN gives (M=Pt or Pd).These complexes are fluxional at 20 deg C due to rapid 'end over end' motion of the dppm ligands.The complex with NaCN gives the binuclear 'face to face' complexes .The platinum complex is quaternized by methyl iodide to give I2.With AgNO3, followed by NaI, gives , with it gives Cl, and with HgCl2 it gives .The complexes (M=Pt or Pd), when treated with , , or trans-, give heterobimetallics of type (M'=Rh or Ir).Treatment of with (C7H8=cyclohepta-1,3,5-triene) gives .I.r. and 31P and 1H n.m.r. data are given.

The cyanide ion is shown to be an excellent ligand for stabilising the fluxional η1-dppm complexes, trans-1-dppm)2> (M = Pt or Pd, dppm = Ph2PCH2PPh2), which can be used as key intermediates in the systematic synthesis of he
