New Group IB chemistry. VI. Syntheses of some acetylenic derivatives of platinum

Abstract

Reactions between CuC₂Ar(Ar = Ph, p-MeC₆H₄, p-FC₆H₄ or C₆F₅) and Pt(C₂H₄)(PPh₃), afforded Pt(C₂Ar)₂(PPh₃)₂, also obtained from PtCl₂(PPh₃)₂ and CuC₂Ar (for Ar = C₆F₅). The acetylene HC₂C₆F₅ reacts with Pt(C₂H₄)(PPh₃)₂ to give Pt(η²-HC₂C₆F₅)(PPh₃)₂ whereas Pt(PR₃)₄ (R = Phor Et) give the hydride-acetylide complexes trans-PtH(C₂C₆F₅)(PR₃)₂
