Cationic Ir(III) alkyl and hydride complexes: stoichiometric and catalytic C-H activation by Cp*(PMe3)Ir(R)(X) in homogeneous solution
This report details our work in the area of C-H activation by cationic Ir(III) complexes. We highlight the previously reported chemistry of transition metal complexes of the type Cp-*(PMe3)Ir(R)(X) (Cp-* is pentamethylcyclopentadienyl or eta(5) -C5Me5; R = alkyl, hydrido; X = OSO2CF3, B(3,5-(CF3)(2)C6H3)(4))), and disclose new results concerning the production of these complexes using Lewis acids (LAs). Additionally, new work aimed at examining the mechanism of C-H activation by these complexes is presented. (C) 2002 Elsevier Science B.V. All rights reserved.
