Synthesis and characterization of novel chiral [(NHC)Au(I)Cl] complexes: Featuring ortho-biphenyl substituents
摘要:
A series of new chiral [(NHC)Au(I)Cl] are synthesized. The chiral NHC ligands feature pairs of orthobiphenyl groups. The distal phenyl groups of the biphenyl substituents are varied from simple phenyl, 3,5-dimethylphenyl, to 3,5-di-t-butylphenyl. X-Ray structure analysis were performed for two such [(NHC) Au(I) Cl] complexes. High percent buried volumes were calculated for two novel chiral [(NHC) Au(I) Cl] complexes whose structure were solved by an X-ray analysis. The rotational motion in the biphenyl group is slow on the NMR time scale. Rotational barriers were determined using WINDNMR for two of the chiral gold complexes. (C) 2015 Elsevier B.V.
