Fischer carbene
E1316662
UNEXPLORED
Fischer carbene is a type of metal–carbene complex in which a low-oxidation-state, often late-transition metal is bonded to a carbene carbon that is typically electrophilic and stabilized by π-acceptor ligands such as carbonyls.

How this entity was disambiguated
This entity first appeared as the object of triple T18288587 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
