Abstract:
The introduction to the first chapter contains a review of the complexes formed during the reactions of hexafluoroacetone and related electrophilic molecules with low-valent metal complexes of the Group VIII transition metals. The reactivity of the complexes is described. The remainder of the chapter is concerned with the preparation of some pi-bonded ketone complexes of platinum of general formula L2Pt (ketone) (L = triphenyl-phosphine, triphenylarsine). The reactions of the ketone complexes with oxygen and a series of electrophilic unsaturated molecules demonstrates that the complexes are more reactive towards ring expansion than the corresponding hexafluoroacetone platinum complex. Reactions of the ketones with peroxobis (triphenylphosphine) platinum are described. Also included in this chapter are the reactions of isatin and benzoyl cyanide with zero-valent platinum complexes. The introduction to the second chapter contains a brief review of olefin to vinyl isomerisation reactions of platinum olefin complexes and a description of results obtained during kinetic studies of such reactions. The second part of the chapter contains results obtained from a kinetic study of the vinyl isomerisation of the olefin complex bromotrifluoroethylenebis (triphenylarsine) platinum to bromo (trifluorovinyl) bis (triphenylarsine) platinum (II).
