A process for the preparation of diaminocyclohexane-platinum(II)- dicarboxylates has the follow- ing steps: B Conversion of K2PtX2 with 1,2-diaminocyclohexane (DACH) to (see formula 2) C Conversion of (2) with too little quantity of silver salt Ag n A to (see formula 3) and removal of the resulting AgX precipitate. (see formula 1) D Conversion of (3) with a dicarboxylate to Isolation of the product (1), whereby R1 and R2 together form a dicarboxylato group, X stands for Cl or I, A for a 1-2-valent anion of a mineral acid and n stands for 1 or 2.
