The isolation and scrutiny of metal carbene complexes is one of the core disciplines of organometallic chemistry and hence lies at the heart of Organometallics. Research has focused for many years on the development of carbon atom transfer reactivity after Fischer’s discovery of heteroatom-stabilized nucleophilic carbene complexes. These efforts culminated in the development of Tebbe’s reagent for methylene transfer as well as the application of carbene catalysts for cyclopropanation, C–H insertion, and the Nobel Prize winning olefin metathesis reaction. The field started to pick up even more speed with the isolation of the first stable acyclic free carbene, reported by Bertrand in the 1980s. Synthesis of Arduengo’s crystalline N-heterocyclic carbene (NHC) in 1991, also known as “bottleable carbene”, eventually demonstrated that persistent carbenes are not merely laboratory curiosities.
