Four tetrahydroquinoline-based chiral carbene precursors were synthesized using unsymmetrical ,'-diarylformamidines and chiral 2-allyloxiranes as starting materials. A representative NHC-gold complex has been prepared and fully characterized, the crystal structure of which reveals an intramolecular Au⋯H-C(sp) interaction between Au(i) and the hydrogen atom of the isopropyl moiety in the -aryl group.
以不对称的N,N'-二芳基甲脒和手性2-烯丙基环氧乙烷为原料，合成了四种基于四氢喹啉的手性卡宾前体。制备并全面表征了一种代表性的NHC-金配合物，其晶体结构揭示了Au(i)与芳基中异丙基部分的氢原子之间存在分子内Au⋯H-C(sp)相互作用。
