Enantioselective transfer hydrogenation of a range of aromatic ketones in 2-propanol catalyzed by chiral Ir(Ⅰ) complexes, prepared in situ from [Ir(COD)Cl]2 and C2- symmetric diaminodiphosphine ligand. The complex acts as an excellent catalyst precursor in asymmetric transfer hydrogenation of isobutyrophenone, leading to optically active alcohol up to 98% yield and 98% ee after 4 h at 25℃ (S/C=1200) 。
