Isolated, cationic bis(cyclooctene)-Ir(I) complexes stabilized by acetonitrile or acetone solvent molecules were obtained and reacted with simple alkylphosphines, leading to selective displacement of the cyclooctene ligand. With the bulky tBu3P, facile intramolecular C-H activation is observed, giving cyclometalated, solvent-stabilized bis(phosphine)-Ir(III) species and leading to the isolation of the first 14-electron alkyl-Ir(III) complex.
