The reaction of dinuclear complex [IrCl(COD)]₂ (COD = 1,5-cyclooctadiene) with 1 equiv of 1,3-dimesitylpropane-1,3-dione (H-Acac^BiMs) and an excess of triethylamine in benzene or dichloromethane at room temperature results in the formation of 尾-diketonate complex [Ir(Acac^BiMs)(COD)], 1. Further, compound 1 reacts with an equivalent of H-Acac^BiMs in dichloromethane under atmospheric conditions to give the new complex with the formula [cis-Ir(Acac^BiMs)₂(COE-OH)], 2 (COE-OH = 蟽,蟺-hydroxyenediyl), through a formal insertion of a hydroxyl group into a COD ring. All compounds were characterized by melting point, analytical data, and IR and NMR spectroscopy. Additionally, an X-ray crystallographic study was undertaken to corroborate the structure of both complexes.
