Disclosed are carbenes of the general formula:
and including salts thereof, and metal complexes thereof. The carbenes are useful in any reaction where carbenes and carbene-metal complexes are used. The carbenes disclosed herein are particularly useful in asymmetric catalysis.

bearing seven-membered NHCs as ancillary ligands. The identity of nitrogen substituent, neopentyl versus 2-adamantyl, influences the synthetic accessibility and stability of the seven-membered amidinium salts and the NHC–metal complexes obtained via in situ deprotonation/metallation. Computational analysis of the seven-memberedring structures reveals the Hückel antiaromatic 8π electron system achieves
