A method is given for the selective synthesis of antitumor platinum greens in a reaction of the hydrolysis products of cis-diiododiammineplatinum (II) and nucleosides via visible-light induced oxidation. A role of singlet oxygen in the green formation is indicated by the sensitized reactions with methylene blue and rose bengal and by experimental quenching of singlet oxygen with 1,4-diaza-bicyclooctane (DABCO).
