<jats:title>Abstract</jats:title><jats:p>Iridium complexes bearing a new type of chiral carbene ligand, cyclic (amino)(ferrocenyl)carbene (CAFeC), were prepared. The complexes, which are quite stable in air and moisture, were fully characterized by NMR spectroscopy and X‐ray diffraction analysis. The NMR spectra of the dicarbonyl complex [IrCl(CO)<jats:sub>2</jats:sub>(CAFeC)] showed signals for two isomers in solution, which were assigned to diastereomeric rotamers arising from the rotation of the chiral CAFeC ligand around the axes of the Ir−C<jats:sub>carbene</jats:sub> bond. IR spectroscopy of the dicarbonyl complex revealed that the donor strength of CAFeC is much higher than those of classic N‐heterocyclic carbenes (NHCs) and comparable to those of cyclic amino alkyl carbenes (CAACs).</jats:p>
