ABSTRACT:
The present invention is a method of preparing tetrachlorodiamine cyclohexane platinum (IV) by reacting a diamine selected from the group consisting of 1,2-diaminocyclohexane and operable isomers thereof in the form of a dihydrohalide with alkali metal or hydrogen hexachloroplatinate. The preferred hexachloroplatinate is potassium salt and the isomers utilized from the diamine are selected from the group consisting of cis, trans (d,l), trans-l, and trans-d. The process noted is where the 1,2-diaminocyclohexane is used in about equimolar amounts with hexachloroplatinate which is subjected to heating at reflux temperature for 12-24 hours in aqueous solvent, cooled and filtered.
