A
hydrocarbon derived from an
arene by
abstraction of two hydrogen atoms from adjacent carbon atoms; thus 1,2-didehydroarene. Arynes are commonly represented with a formal triple bond. The analogous
heterocyclic compounds are called
heteroarynes or
hetarynes. For example, benzyne:
Arynes are usually transient species.
