Abstract

Square-planar iridium complexes of the large but strongly donating PCy3 (Cy = cyclohexyl) ligand, trans-Ir(CO)(Cl)(PCy₃)₂ and trans-Ir(CO)(OH)(PCy₃)₂, have been reacted with the molecules O₂, H₂, Cl₂, and SO₂. In comparison to the analogous PPh₃ complexes, the presence of PCy₃ inhibits reactions with H₂ and O₂ but has little effect on reactions with Cl₂ and SO₂. In the latter two reactions the greater electron density compensates for the larger size of the PCy₃ ligands. Reaction of SO₂ with trans-Ir(CO)(OH)(PCy₃)₂ leads to an oxygen-coordinated hydrogen sulfite ligand, and the structure was determined. The molecules exist in the crystals as weakly bound dimers.
