Abstract

An improved synthesis of a water-soluble phosphine ligand, PPh₂(CH₂CH₂NMe₃⁺I ^-) amphos, is reported. Iridium complexes with amphos, trans-Ir(CO)X(amphos)₂ (X = Cl, I), Ir(CO)(H) (amphos)₃ and Ir(CO)₃(amphos)₂⁺ have been prepared and examined for reactions with H₂ and CO. Structures of trans-Ir(CO)(Cl)(PPh₂CH₂CH₂NMe ₂)₂ and [trans-Ir(CO)(Cl) (PPh₂CH₂CH₂NMe₃⁺) ₂][I^-]₂·2DMSO are compared to each other and to trans-Ir(CO)(Cl) (PPh₃)₂. The amphos ligand changes the solubility of iridium complexes, but does not markedly change the nature of the iridium center. Reactions show the effects of more polar solvents.
