Abstract
The reactions of [Pt(dppf)Cl2] with thiophenol (PhSH), 1-propanethiol (n-PrSH), and 1,3-propanedithiol (HSCH2CH2CH2SH) gave the corresponding Pt-dppf-di(thiolato) compounds, [Pt(dppf)(SPh)2] (1), [Pt(dppf)(S-n-Pr)2] (2), and [Pt(dppf)(SCH2CH2CH2S)] (3), respectively. All products are monomeric and 4- coordinate square-planar compounds and were structurally characterized by X-ray diffraction. Electrochemical measurements (cyclovoltammograms) revealed that the oxidation potential of the dppf ligand appears to depend on the type of the group on the thiolato ligand.
