Flip the switch! The facile and distinct variation of the electronic properties of an N‐heterocycliccarbene (NHC) ligand is reported. In this process, a simple deprotonation/protonation strategy can render the NHC to be an electron‐poor or an electron‐rich NHC ligand: one ligand, two electronic natures.
