Iridium cyclopentadienyl cations

An efficient regio- and stereoselective organometalUc method to nucleophilic phenol ortljo-lhnctionahzation promoted by a cyclopentadienyl iridium cation ([Cp Ir] +, where Cp is CsMes) was reported by Amouri and coworkers (equation 47) (the electrophilic phenol Ihnctionalization by means of electron-rich moiety [Os(NH3)5] was mentioned above , see Section n.A.4).

COE L2 = C7H8, 1,5-COD) were obtained in good yields by reaction with the corresponding iridium(l) chloride precursors (Scheme 95). Intramolecular charge-transfer process between the photoexcited 9-anthracenyl group and the cyclopentadienyl metal unit was invoked to explain the observed anthracenic fluorescence quenching and was studied by detailed EPR characterization of the corresponding cation radicals. ... 

The role of the cyclopentadienyl ligand in the a-bond activation of methane by [Co(ri -C5H5)] has been studied and a reaction mechanism proposed which includes several intermediates containing Co-alkyl bonds.A series of Ir-Me species have been synthesised as part of an investigation into the effect of the hydridotris(pyrazolyl)borate ligand on C-H bond activation by cationic iridium complexes. The rhodium species 23 has been synthesised as part of a study into...
