    • A process for the preparation of cis-platinum (II) complexes of 1,2-cyclohexanediamine isomers not contaminated with any dihydroxoplatinum (IV) complex. Specifically, a process for preparing cis-platinum (II) complexes of 1,2-cyclohexanediamine isomers represented by general formula (I) from potassium chloroplatinate and trans-(-)-1,2-cyclohexanediamine as the raw materials, wherein the water used in the steps of preparing the platinum compounds from the raw materials is a deoxygenated one and the preparation is conducted in a low-oxygen-concentration atmosphere to inhibit the deoxygenated water from being deteriorated by the absorption of oxygen and to inhibit the platinum compounds from being directly oxidized by atmospheric oxygen.
    • 制备未被任何二羟基铂(IV)络合物污染的1,2-环己烷二胺异构体顺式 - 铂(II)络合物的方法。 具体地说,制备由氯铂酸钾和反 - ( - ) - 1,2-环己二胺为原料的由通式(I)表示的1,2-环己二胺异构体的顺 - 铂(II)络合物的方法,其中水 用于从原料制备铂化合物的步骤是脱氧的,并且在低氧浓度气氛中进行制备以抑制脱氧水被氧吸收而劣化并抑制铂化合物 被大气氧直接氧化。
