This invention relates a method for the preparation of platinum(II) oxalato complexes from their dihalogenoplatinum(II) precursors having either neutral monodentate or bidentate non-leaving co-ligands. Of particular interest is oxaliplatin. The method includes the step of reacting a halogenoplatinum(II) complex containing a neutral monodentate or bidentate ligand with an oxalate in a non-aqueous solvent or a mixed solvent system. The mixed solvent system is solvent mixture containing a non-aqueous solvent and water. According to the present invention, the non-aqueous solvent is an alcohol.

Two methods for the synthesis of compounds of the type cis-PtA2X2 (A2 = bidentate amine or two monodentate amines and X2 = bidentate or two monodentate carboxylato ligands) were evaluated. The compounds were characterized by multinuclear NMR and IR spectroscopies. The 195PT NMR chemical shifts were in the range - 1615 to - 1976 ppm, the higher field values corresponding to the complexes containing bidentate ligands. The coupling constants 3J(195Pt-1H) are approximately 35 Hz, while the 2J(195Pt-1HN) are about 70 Hz. One coupling constant 2J(195Pt-13C) (53 Hz) was also measured. The crystal structure of the compound, cis-Pt(1,1-cyclobutanedicarboxylato)(C2H5NH2)2·H2O belongs to the P21/n space group with a=9.468(5), b =9.365(4), c = 16.473(7) A?, β = 105.08(3)°, Z = 4 and R1 = 0.0576. The Pt-N bond distances are 1.992(5) and 2.020(5) A?, while the Pt-O bonds are 2.000(4) and 2.015(4) A?. The molecules are held together by intermolecular H-bonds involving the lattice water molecules and the two free carbonyl O atoms and between the amino H atoms and the Pt-bonded C-O groups.

The interaction between cis-dichlorodiammineplatinum(II) and urotropin is studied in an aqueous solution. Complexes of compositions [Pt2(NH3)4Ur3]Cl4 and [Pt2(NH3)4Ur3][PtCl4]2 (Ur = urotropin), which are confirmed by elemental analysis, are isolated from the solution. Procedures for purification of the Peronnet salt and the preparation of oxalatodiammineplatinum(II) are developed.
