The construction of a borole ring that is part of a metal complex from zirconium-coordinated 1,3-dienes and tris(pentafluorophenyl)borane has been recently introduced. Tris(pentafluoro-phenyl)borane is widely used as an activator of metallocene-based polymerization catalysts because of its resistance to aryl-transfer reactions, it acts as the boron source. The reaction utilizes the zwitterionic 14-electron bis(allyl)zirconium complexes 72 and 73 which are converted to the corresponding complexes 74 and 75 via activation of one of the C-H bonds of the B-CH2 moiety... 

Dimethyl(pentafluorophenyl)phosphine and dimethyl(pentafluorophenyl)-arsine form stable complexes with transition metals, for example, Pt(II), Pd(II), Ni(II), Au(I), and Co(II),i> and they are particularly interesting ligands for stereochemical studies, as both and F nmr spectra are sensitive indicators of the coordination environment of the ligand. These pentafluoro-phenyl ligands can be prepared by the following procedures in approximately 15-hr working time with an elapsed time of 30 hr. 

The reaction of iodobenzene with pentafluoroaniline in the presence of 3% PdCl2-(PPh3)2 and 1.2 equivalent of l,8-diazabicyclo[5.4.0]undec-7-ene in /V,/V-dimethyla-cetamide in the presence of carbonmonoxide forms 2-aryl-4,5,6,7-tetrafluorobenz-oxazole (92JOC6351) (Scheme 146). The reaction probably occurs via the intermediate formation of a palladium complex and N-pentafluoro-phenyl-benzamide. 

Reaction of bis(pentafluorophenyl)acetylene with the rhodium complex [(Tr-CsHjIRhfCO) ] in refluxing toluene or xylene yields hexakis(pentafluoro-phenyl)benzene (40—70%), together with several rhodium complexes including [(7r-C5H5)3Rh3(CO)(C,F -C C-C,Fj)] and the cyclopentadienone complex (222). ...

A number of new palladium complexes containing pentafluoro-phenyl or pentachlorophenyl ligands have been reported. Thus, for example, complexes of the type [(CgFg)2Pd(p-Cl)2ML2] (M = Ni.Pd ... 

The isocyanide cation [CpFe(CO)(CNMe)2] reacts with pentafluoro-phenyl-lithium to give the cr-aryl complex [CpFe(CNMe)2(C F5)] and the imlne complex CpFe(CO)(CNMe)[C(CeF6) NMe], in which attack at the isocyanide ligand has occurred. The latter complex consists of two isomers, one of which slowly isomerises to the other, which in turn loses carbon monoxide to give CpFe(CNMe),(C F6). With the mono-isocyanide cation [CpFe(CO)j(CNMe)]+, attack occurs on the cyclopentadienyl ring to give...
