WebThe Fischer-type carbene complexes are low-valent complexes stabilized by strong π-accepting ligands (often CO). One or two heteroatoms (O, N, or S) are bonded to the carbene carbon atom and stabilize it by delocalizing the positive formal charge. The carbene is formally regarded as a neutral ligand. A Fischer carbene is a type of transition metal carbene complex, which is an organometallic compound containing a divalent organic ligand. In a Fischer carbene, the carbene ligand is a σ-donor π-acceptor ligand. Because π-backdonation from the metal centre is generally weak, the carbene carbon is … See more A metal carbene complex could be considered a Fischer carbene when the carbene is in singlet state. Delocalization of the lone pair from the substituent on carbene carbon raises the energy of pz orbital, thus forcing … See more The most common strategy to prepare a Fischer carbene is reaction between a metal carbonyl complex with organolithium compounds. The corresponding lithium enolate-like … See more • Wulff–Dötz reaction See more Carbonyl-like reactivity The carbene carbon of a Fischer carbene is electrophilic in nature.
