Preparation and substitution reactions of (diphosphine)platinum(II) carboxylate complexes

[Pt(OCOPh)2(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane), [Pt(mal)(dppe)] (mal = malonate), and [Pt(mal)(dppm)] (dppm = bis(diphenylphosphino)methane) are prepared by treatment of [PtCl2(dppe)] or [PtCl2(dppm)] with AgOCOPh or Ag2(mal). [Pt(OCOPh)2(dppe)] reacts with P-W-Bu3 to yield [Pt(OCOPh)(P-n-Bu3)(dppe)]+, which subsequently reacts with chlorinated solvents to produce [PtCl(P-n-Bu3)(dppe)]+. Analogously, [Pt(mal)(dppe)] gives [PtCl(L)(dppe)]+ when treated with P-n-Bu3, PEt3, or PMePh2. In the case of L = P-n-Bu3 the intermediate [Pt+(OCOCH2COO-)(P-n-Bu3)(dppe)] is observed spectroscopically at low temperature and may be protonated with HClO4. The ease of substitution of dicarboxylate or diphosphine ligands is investigated by allowing [Pt(O O)(P P)] (O O = C2O4, mal; P P = dppe, dppm) to react with P-n-Bu3. [Pt(mal)(dppm)] reacts with 2 molar equiv of P-n-Bu3 or PMePh2 to give ion-paired species of the form [Pt(L)2(dppm)][mal].
