Abstract

Steric and electronic effects of phosphine ligands on binding of molecules to iridium(I) have been probed by studying reactions of O₂, SO₂ and CH₃I with trans-Ir(CO)(Cl)(P(i-Pr)₃)₂ and trans-Ir(CO)(Cl)(P(t-Bu)₂Me)₂ for comparison to known reactions with trans-Ir(CO)(Cl)L₂ (L = PPh₃, P(p-tolyl)₃ and PCy₃). Reaction of O₂ is significantly retarded by increasing size of the ligand while reaction of SO₂ is essentially unaffected by the nature of the phosphine ligand. Reaction of CH₃I with trans-Ir(CO)(Cl)(P(t-Bu)₂Me)2 produces two products which have been characterized by NMR and infrared spectroscopy.
