Planar-Chiral Ferrocene-Based N-Heterocyclic Carbene Ligands.
Yoshida K, Yasue R. Yoshida K, et al. Chemistry. 2018 Dec 12;24(70):18575-18586. doi: 10.1002/chem.201803903. Epub 2018 Nov 28. Chemistry. 2018. PMID: 30277615 Review.
This review documents advances in chiral NHC ligands, focusing on planar-chiral ferrocene-based NHCs. As the basic shape of most classes of NHC rings is planar, it seems rational to employ a planar-chiral element in the design of chiral NHC ligands....
