Abstract

The complexes PtR₂(diene) (R = C₆F₅ or p-HC₆F₄; diene = cis,cis-cycloocta-1,5-diene (cod), dicyclopentadiene (dcy), norbornadiene (nbd) or hexa-1,5-diene (hex)) have been prepared by the organolithium route. Reaction of PtCl₂(cod) with an equimolar amount of TlO₂CR (R = C₆F₅ or p-HC₆F₄) in pyridine yields Pt(R)Cl(cod), which have been converted into Pt(R)X(cod) (X = Br or I) by halogen exchange reactions. Other decarboxylations result in diene displacement giving cis-Pt(C₆F₅)Cl(py)₂ and cis- and trans-Pt(C₆F₅)₂(py)₂. The complexes, cis-Pt(C₆F₅)₂L₂ (L = py or Ph₃P) and cis-Pt(p-HC₆F₄)₂(PPh₃)₂) are formed by ligand replacement reactions of PtR₂(cod), but Pt(C₆F₅)₂(cod) does not react with N,N,N′,N′-tetramethylethylenediamine (tmed) nor Pt(C₆F₅)₂(nbd or dcy) with ethylenediamine (en). Diene displacement occurs more readily from PtR₂(hex) giving Pt(C₆F₅)₂L₂ (L₂ = cis-(NH₃)₂, en, tmed or 1,10-phenanthroline) and cis-Pt(p-HC₆F₄)₂(PPh₃)₂.
