Sensitized photooxidation of 4-phenyl-1,2-dithiolane 1 has been studied. Reacting it with 0.5 mole equivalents o f singlet oxygen, a mixture of 1, 4-phenyl-1,2-dithiolane-1-oxide 2, and 4-phenyl-1,2-dithiolane-2-dioxide 3 is produced. Using one mole equivalent of singlet oxygen, 3 is obtained in high yields. The chemical oxidation of 1 using H2O2/HOAc yields pure 2. With 2 a diastereoselectivity of 10:1 is observed. The oxidative addition of 1 to L2Pt(η2-C2H4)[L=PPh3 (4), 1/2 dppe (5)] leads to the 3-phenyl-propane dithiolato complexes 6a,b. The platinum(O) com pound 4 reacts with 2 to give the bimetallic compound 7 and the monometallic species . These complexes contain the 3-sulfido-l-(2-phenyl)-propanesulfenato ligand. All com pounds have been characterized by their spec­ troscopic data.
