Abstract
The preparation and properties of (1,2-diaminocyclohexane)dichloroplatinum(II) complexes containing cis and trans 1,2-diaminocyclohexane were studied, and the separation of the isomers from their mixture was investigated. Separation in the form of the nickel(II) complexes was chosen with regard to its efficiency and to the possibility of obtaining directly the corresponding 1,2-diaminocyclohexane hydrochloride. Good quality products were obtained in a yield of more than 90% by reacting 1,2-diaminocyclohexane dihydrochloride with K2[PtCl4] in aqueous solution, pH ca 10, in dark at room temperature.
