摘要：The Ir-NHC complex 6 was successfully synthesized from the reaction of axially chiral binaphthyl dibenzimidazolium salt 5 with [Ir(COD)Cl](2) (COD = 1,5-cyclooctadiene) in tetrahydrofuran in the presence of (KOBu)-Bu-t base under reflux. Its unique crystal structure is unambiguously disclosed by X-ray diffraction. Complex 6 is orthorhombic, with space group P2(1)2(1)2(1), unit cell dimensions a = 12.1406(16) Angstrom, b = 19.110(3) Angstrom, c = 20.312(3) Angstrom, alpha = beta = gamma = 90degrees and volume 4712.6(11) Angstrom(3), Z = 4, D-calc = 1.930 Mg m(-3).
