    • 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.
    • 本发明涉及从具有中性单齿或双齿不离开共配体的二卤代铂(II)前体制备草酸二(II)配合物的方法。 特别感兴趣的是奥沙利铂。 该方法包括使含有中性单齿或二齿配位体的卤代铂(II)络合物与草酸盐在非水溶剂或混合溶剂体系中反应的步骤。 混合溶剂体系是含有非水溶剂和水的溶剂混合物。 根据本发明,非水溶剂是醇。

    • The invention relates to a method for the preparation of platinum (II) complexes, in particular dicarboxylatoplatinum (II) complexes containing a neutral bidentate ligand, such as oxaliplatin. The method includes the step of reacting a bis-dicarboxylatoplatinate (II) species with a suitable neutral bidentate ligand to form a neutral dicarboxylatoplatinum (II) complex and, if necessary, recrystallizing the product to form a pure dicarboxylatoplatinum (II) complex containing a neutral bidentate ligand. The invention also relates to a method for producing a bis-dicarboxylatoplatinate (II) species, and to new platinum (II) complexes that can be made by the method of the invention.
    • 本发明涉及一种制备铂(II)络合物,特别是含有中性二齿配体如奥沙利铂的二羧酸铂(II)络合物的方法。 该方法包括使双 - 二羧基化合物(II)物质与合适的中性二齿配位体反应形成中性二羧酸铂(II)络合物的步骤,如果需要,将产物重结晶以形成含有中性的二羧酸铂(II)络合物 二齿配体。 本发明还涉及一种生产双 - 二羧基化合物(II)物质的方法,以及可以通过本发明的方法制备的新的铂(II)络合物。
