Axially chiral mono(NHC)–Pd(II) and mono(NHC)–Au(I) complexes with one side shaped 1,1'-biphenyl backbone have been prepared from chiral 6,6'-dimethoxybiphenyl-2,2'-diamine. The complexes were characterized by X-ray crystal structure diffraction. The Pd(II) complex showed good catalytic activities in the Suzuki–Miyaura and Heck–Mizoroki coupling reactions, and the (S)-Au(I) complexes also showed good catalytic activities in the asymmetric intramolecular hydroamination reaction to give the corresponding product in moderate ee.
具有轴向手性的单(NHC)-Pd(II)和单(NHC)-Au(I)配合物,具有一侧成形的1,1'-联苯骨架,已经从手性6,6'-二甲氧基联苯-2,2'-二胺制备而成。这些配合物通过X射线晶体结构衍射进行了表征。Pd(II)配合物在Suzuki-Miyaura和Heck-Mizoroki偶联反应中表现出良好的催化活性,而(S)-Au(I)配合物在不对称分子内氢胺化反应中也表现出良好的催化活性,以适度的ee产生相应的产物。
