The cyclometallation of benzoic acid and the X-ray crystal structure of [C5Me5Ir(O2CC6H4)(Me2SO)]
Abstract
The complexes [C5Me5M(C6H4CO2)(Me2SO)](1a, M = Rh; 1b, M = Ir), and [(p-cymene)Os(C6H4CO2)(Me2SO)], containing cyclometallated benzoic acid, have been prepared and characterised; carbonylation of (1a) yields phthalic anhydride.
