Abstract

New water soluble alkyl iridium(I) complexes were synthesized and their reaction with small molecules (H₂, CO and O₂) in DMSO or H₂O examined. Hydrogenation of trans-Ir(CH₃)(CO)(TPPMSK)₂ [TPPMSK = (P(C₆H₅)₂(m-C₆H₄SO ₃K)₂] in DMSO produced CH₄ and Ir(CO)(H)(TPPMSK)₃ as major products. Carbonylation of trans-Ir(CH₃)(CO)L₂ (L = TPPMSK or TPPMS [TPPMS = P(C₆H₅)₂(m-C₆H₄SO ₃Na)]), in DMSO, produced Ir(C(O)CH₃)(CO)₂L₂. Reactions in water were complicated by rapid hydrolysis of the Ir - CH₃ bond forming CH₄ and trans-Ir(CO)(OH)L₂. The hydrolysis was inhibited by excess L allowing the reactions to be studied in water.
