摘要：

Solutions containing unstable organopalladium(IV) complexes of phosphines, [PdMe3(bpy)(L)](+) (L = PMePh2, PMe2Ph, PPh3), are generated on reaction of PdIMe3(bpy) with the phosphines in dichloromethane-d(2). The complex [PdMe3(bpy)(PPh3)](+) may also be formed quantitatively on the reaction of PdMe2(bpy) with methyl triflate and triphenylphosphine in acetone-d(0). A solution of the platinum(IV) analogue [PtMe3(bpy)(PPh3)][O3SCF3] is formed following a similar procedure and isolated as crystals on reaction of PtIMe3(bpy) with silver triflate followed by PPh3. An X-ray structure determination of the platinum(IV) complex shows the fac-PtMe3 configuration for octahedral [PtMe3(bpy)(PPh3)](+), and supports the assignment of identical structures for the unstable palladium(IV) complexes from comparison of H-1- and P-13-NMR spectra of palladium(IV) and platinum(IV) complexes.
