Abstract

On treatment with silver nanoparticles [Cp∗IrCl2(κC-MeNC3H2NCH2C6H4F-2)] underwent CH bond activation to afford the orthometallated product [Cp∗IrCl(κC2-MeNC3H2NCH2C6H3F-6)] exclusively. The same product was obtained from [Cp∗IrCl2(κC-MeNC3H2NCH2C6H4F2-2,6)] by CF bond activation. Treatment of [Cp∗IrCl2(κC-MeNC3H2NCH2C6H3F-2-X-6)] (X = Cl, Br, I) with silver nanoparticles induced CF and CX bond activation to yield mixtures of the orthometallated products [Cp∗IrCl(κC2-MeNC3H2NCH2C6H3F-6)] and [Cp∗IrCl(κC2-MeNC3H2NCH2C6H3X-6)]. The structures of the products, which are isostructural and co-crystallized, have been determined by single crystal X-ray diffraction.
