Syntheses, Spectra, and Structures of (Diphosphine)platinum(II) Carbonate Complexes

A variety of (diphosphine)platinum(II) carbonate complexes, (LL)Pt(CO3), are readily prepared from the corresponding (diphosphine)platinum dichlorides by treatment with silver carbonate in dichoromethane solution provided that water is present. This reaction also permits facile preparation of analogous 13C-labeled complexes. The carbonate ligands in these complexes have been characterized by IR and 13C NMR spectroscopy. Alternative preparative routes involve conversion of the precursor dichlorides to the corresponding dialkoxides or diphenoxides, followed by treatment with water and carbon dioxide. Various reaction intermediates have been spectroscopically observed in the latter syntheses. Two crystalline modifications of (Ph2PCH2CH2CH2PPh 2)Pt(CO3), one with and one without a dichloromethane of solvation, have been studied by single-crystal X-ray diffraction. Crystal data for PtP2O3C28H26: P21/c, Z = 4, T = 200 K, a = 10.362(8) ?, b = 14.743(6) ?, c = 19.183(10) ?, β = 122.69(6)°. Crystal data for PtP2O3C28H26·CH 2Cl2: P21/c, Z = 4, T ≈ 298 K, a = 11.744(2) ?, b = 15.526(3) ?, c = 15.866(3) ?, β = 101.58(1)°.

Regioselective complexation of unprotected carbohydrates by platinum(II): Synthesis, structure, complexation equilibria, and hydrogen-bonding in carbonate-derived bis(phosphine)platinum(II) diolate and alditolate complexes

Treatment of bis(phosphine)platinum(II) carbonate complexes (LL)Pt(CO3) (e.g., LL = 1,3-bis(diphenylphosphino)propane) with vicinal diols (i.e., HOCR1R2CR3R4OH) gives equilibrium conversion to the corresponding diolate complexes (LL)Pt(OCR1R2CR3R4O), which are readily isolated in good yield. From competition experiments, relative diol complexation constants were determined as a function of both the diol and the phosphine substituents and found to span a range of over 104. Corresponding triolate and alditolate complexes were similarly prepared, for which very distinct equilibrium isomeric regioselectivities are observed, favoring complexation of γ,δ-threo diols. An X-ray structure of (dppp)Pt(D-mannitolate) shows that the mannitol is bonded to the platinum as its dianion via the oxygens on C3 and C4 to form a 2,5-dioxaplatinacyclopentane chelate ring and that three different strong intramolecular hydrogen-bonding interactions are present between the hydroxyl hydrogens and the metallacycle oxygens (O?O (av) = 2.65(2) A?), forming five-, six-, and seven-membered rings. Crystal data for PtP2O6C33H38·CH 2CI2: P212121, Z = 4, T ≈ 20 °C, a = 11.225(2) A?, * = 15.875(3) A?, c = 19.964(4) A?, R(Fo) = 0.058, Rw(Fo) = 0.062.
