Catalytic Transfer of Magnetism using a Neutral Iridium Phenoxide Complex.

ABSTRACT: A novel neutral iridium carbene complex Ir(κC,O-L₁)(COD) (1) [where COD = cyclooctadiene and L₁ = 3-(2-methylene-4-nitrophenolate)-1-(2,4,6-trimethylphenyl) imidazolylidene] with a pendant alkoxide ligand has been prepared and characterized. It contains a strong Ir-O bond and X-ray analysis reveals a distorted square planar structure. NMR spectroscopy reveals dynamic solution state behavior commensurate with rapid seven-membered ring flipping. In CD₂Cl₂ solution, under hydrogen at low temperature, this complex dominates although it exists in equilibrium with a reactive iridium dihydride cyclooctadiene complex. 1 reacts with pyridine and H₂ to form neutral Ir(H)₂(κC,O-L₁)(py)₂ which also ex
