The hydroxo complexes [NBu4]2[{M(C6F5) 2(μ-OH)}2] (M = Pd, Pt) react with phenols ROH (1:2 molar ratio) to give the bis(μ-aryloxo) complexes [NBu4]2[{M(C6F5) 2(μ-OR)}2] (M = Pd, Pt; R = C6H5, p-MeC6H4, p-NO2C6H4, C6F5). The reaction of bis(μ-aryloxo) complexes with PPh3 (1:2 molar ratio) gives the aryloxo monomer complexes [NBu4][M(C6F5)2(OR)(PPh 3)] (M = Pd, Pt; R = p-NO2C6H4, C6F5). The platinum monocarbonyl complexes [NBu4][Pt-(C6F5)2(OR)(CO)] (R = p-NO2C6H4, C6F5) have also been prepared by reaction of the corresponding bis(μ-aryloxo) complexes with carbon monoxide at room temperature and normal pressure. [NBu4][Pd(C6F5)3(CO)] is isolated in low yield from the reaction of [NBu4]2Pd(C6F5) 2(μ-OC6H4NO2-p)] with CO in the presence of water. The identity of the isolated complexes has been established by partial elemental analyses, conductance measurements, and spectroscopic (IR, 1H, 19F, 31P) methods. A single-crystal diffraction study of [NBu4][Pt(C6F5)2(OC 6H4NO2-p)(CO)] showed that coordination about platinum was approximately square-planar with the aryl rings tilted to avoid steric crowding.
