Synthesis and Characterization of Hydridoirida-β-diketones Formed by the Reaction of [{Ir(Cod)Cl}2] (Cod = 1,5-cyclooctadiene) witho-(Diphenylphosphino)benzaldehyde

[{Ir(Cod)Cl} 2 ] (Cod = 1,5-cyclooctadiene) reacts with o -(diphenylphosphino)benzaldehyde (PPh 2 ( o -C 6 H 4 CHO)) (Ir:P = 1:2) in methanol to give the hydridoirida-β-diketone complex [IrH{(PPh 2 ( o -C 6 H 4 CO)) 2 H}Cl] ( 1 ). The reactivity of 1 to afford neutral and cationic hydridoirida-β-diketones is also discussed
