Cover Feature: Coordination Behavior of a Planar Chiral Cyclic (Amino)(Ferrocenyl)Carbene Ligand in Iridium Complexes (Chem. Eur. J. 66/2017)

Owing to their unique electronic properties, N‐heterocyclic carbenes (NHCs) have attracted much attention as powerful ligands in transition‐metal catalysis. However, the development of effective chiral NHCs remains a challenge, as the flat heterocyclic structures typically used are challenging to design. Herein, coordination behavior of a new chiral NHC, cyclic (amino)(ferrocenyl)carbene (CAFeC), was examined. Full characterization of its iridium complexes revealed that CAFeC has a strong coordination ability, surpassing that of classic NHC ligands, as well as a promising planar chiral environment. These fundamental data are expected to further advance the development of CAFeC ligands. More information can be found in the Full Paper by Y. Shikata, R. Yasue, and K. Yoshida on page 16806.
