 Title    Metallkomplexe mit funktionalisierten Schwefelliganden, VIII [1] 4-Phenyl-l,2-dithiolan-l-oxid, ein stabiles, fünfgliedriges cyclisches Thiosulfinat Metal Complexes o f Funetionalized Sulfur Containing Ligands, VIII [1] 4-Phenyl-1,2-dithiolane-l-oxide, a Stable, Five-Membered Cyclic Thiosulfinate  
 Abstract    Sensitized photooxidation of 4-phenyl-l,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-l-oxide 2, and 4-phenyl-l,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 H 20 2/H 0 A c yields pure 2. With 2 a diastereoselectivity of 10:1 is observed. The oxidative addition of 1 to L2Pt 072-C-,Hd) [L = PPh, (4), 1/2 dppe (5)] leads to the 3-phenyl-propane dithiolato complexes L?P t-S -C H ,-C H P h -C H -,-S 6a,b. The platinum(O) com pound 4 reacts with 2 to give the bimetallic compound [(P h ,P)P t-S (0)-C H T -C H P h -C H -,-/i-S ^ 7 and the monometallic spe­ cies c/s-(Ph3P)2P t -S (0) -C H 2-C H P h -C H 2-$ 8. These complexes contain the 3-sulfido-l-(2-phenyl)-propanesulfenato ligand. All com pounds have been characterized by their spec­ troscopic data.
