Abstract

Several new water-soluble iridium(I) complexes were synthesized and their reactivities with small molecules (H₂ or CO) in polar solvents (DMSO or H₂O) examined. Reaction of H₂ with [Ir(CO)(TPPMS)₃]CF₃SO₃ (TPPMS = P(C₆H₅)₂(m-C₆H₄SO ₃K)) in DMSO or H₂O produces [cis,mer-Ir(CO)(H)₂(TPPMS)₃]CF₃SO₃, while the reaction of CO with [Ir(CO)(TPPMS)₃]-CF₃SO₃ in water yields [Ir(CO)₂(TPPMS)₃]CF₃SO₃. Carbonylation of [Ir(CO)₂(TPPMS)₃]ClO₄ in DMSO produces [Ir(CO)₃(TPPMS)₂]ClO₄ and TPPMS; no reaction is observed in H₂O. Hydrogenation of [Ir(CO)₂(TPPMS)₃]ClO₄ in DMSO or H₂O yields [cis,mer-Ir(CO)(H)₂-(TPPMS)₃]ClO₄, while reaction of H₂ with an aqueous solution of [Ir(CO)(H₂O)(TPPTS)₂]-CF₃SO₃ produces [Ir(CO)(H₂O)(H)₂(TPPTS)₂]CF₃SO ₃. Reaction of trans-Ir(CO)ClL₂ (L = TPPMS or TPPTS) with excess L in H₂O produces [Ir(CO)L₃]Cl, while no reaction occurs in DMSO. [Ir(CO)₃(TPPMS)₂]Cl reacts irreversibly with TPPMS in H₂O to produce [Ir(CO)₂-(TPPMS)₃]Cl.
