η-Bonded ketone complexes of platinum(0). The preparation of complexes of chloropentafluoropropan-2-one and 1,3-dichlorotetrafluoropropan-2-one and the kinetics of isomerisation of [Pt(η-Cf3COCF2Cl)(PPh3)2] to cis-[PtCl(CF2COCF3)(PPh3)2]
Abstract
The preparation and characterisation of the η-bonded ketone complexes [Pt(η-CF2ClCOCF2X)(PPh3)2](X = For Cl) are reported. The complexes isomerise in solution to cis-[PtCl(CF2COCF2X)(PPh3)2]. The kinetics of isomerisation of [Pt(η-CF2ClCOCF3)(PPh3)2] are described, and the isomerisation mechanism discussed.
