Zusammenfassung

Treatment of the dinuclear doubly alkynyl bridged diplatinum complex [trans-Pt(μ-η<sup>1</sup>:η<sup>2</sup>-C≡CR)-(C 6F5)(PPh3)]2 (2; R = CEtMeOH) with HSPh leads to the formation of the novel thiolate cyclobutene-diylidene heterobridged diplatinum complex {cis-(PPh3)-(C6F 5)Pt[μ-..-C..-(CEtMeOH)..-C(C=CEtMe)](μ-SPh)-Pt(C 6F5)(PPh3)} (3), which is formed by an unexpected net [2 + 2] cycloaddition reaction. This is the first example of a homobinuclear complex containing a cyclic C4(=CR′R″)R unsaturated bridging ligand.
