Photo-and-Thiol-Driven Trans Insertion of Phenylacetylene into H−Pt Bonds
摘要:
The photo-and-thiol-driven trans insertion of phenylacetylene into H-Pt bonds of Pt(X)(H)(PPh3)2 (X = SAr, Cl, Br, and I) took place to afford Pt[(Z)-C(H)=CH(Ph)](X)(PPh3)2 in good yields.
The principle of C–S bond activation of acyclic vinlyl sulfide by platinum(0)-complex was applied to the C–Se bond fission of vinyl selenide. The substrate possessing Ph and ArSe (Ar = C6H4Cl-p) substituents at the β-carbon successfully reacted with Pt(0)-complex at 25 °C to produce the vinyl platinum in good yield and its structure was unambiguously determined by X-ray crystallographic analysis.
