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) magnified image 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 magnified image (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°.
