  Synthesis of Chiral C 1-Symmetric N-Heterocyclic Carbene Ligands: Application toward Copper-Catalyzed Homocoupling of 2-Naphthols

  摘要：

  Novel chiral C-1-symmetric NHC ligands can be prepared via dialkylation of chiral imidazoline scaffolds. Asymmetry in the ligand/metal complexes results from a chiral relay effect. The C-1-symmetric nature of the NHC ligand was proposed to allow for improved reactivity versus other achiral and chiral NHC complexes. The benefit of such ligands was demonstrated in copper-catalyzed oxidative coupling reactions.
