| PATENT CLAIMS |
Process for prepn of Pt(II) complex of 1,2-cyclohexanediami ne isomer represented by formula - Cyclohexane-1,2-Di-NH2 . Pt(II) . -O-CO-CO-O- (R,R') wherein the steric configuration of 1,2-cyclohexanediamine is cis, trans-d, or trans-1 & R,R' form cyclic structure with Pt(II) to represent -O-CO-CO-O- etc, the process comprising - Use of deoxygenating water in all steps for obtaining Pt compd from K tetrachloroplatinate & trans-(-)-1,2-cyclohe xanediamine serving as starting materials - Substituting N for air of an operational environment to thereby produce low-O content atm. so as to prevent degradation of deoxygenated water & to eliminate possibi lity of direct oxidation of Pt compd due to O contained in air |
