Metal Complexes of Functionalized Sulfur-Containing Ligands, III[1]. - Reactions of (Ph3P)2Pt(η2-C2H4) with Acyclic and Cyclic Thiosulfinates: Platinum(II)-thiolato Complexes with Sulfenato Ligands. Crystal Structure Determination of (4-Sulfido-1-butanesulfenato-S,S′)bis(triphenylphosphane)platinum(II) Oxidative addition of acyclic thiosulfinates R′-S(O)-S-R (1a: R′ = R = CH3; 1b: R′ = R = Ph; 1c: R′ = R = p-CH3C6H4;1d: R′ = p-ClC6H4, R = C6H5) to (Ph3P)2Pt(η2-C2H4) (4) leads to the monomeric trans-configurated complexes (Ph3P)2Pt[S(O)R′](SR) (5a-d) which loose one PPh3 ligand in solution and form the dimetallic thiolato-bridged compounds [(Ph3P)Pt[S(O)R′](μ-SR)]2. The cyclic thiosulfinates 1,2-dithiane S-oxide (2) and 1,4-dihydro-2,3-benzodithiine S-oxide (3) react with 4 to yield the monomeric seven-membered chelate (7) and the dimetallic complex [(Ph3P)Pt-S(O)-CH2-C6H4-CH2-μ-S]2 (8), respectively. In 7, characterized by X-ray diffraction, a tetrahedral distortion of the square planar coordination of the platinum(II) atoms is remarkable; the planes Pt,P(1),P(2) and Pt,S(1),S(2) form an angle of 16.1°.
