Species, usually transient, derived formally by the abstraction
of a hydrogen atom from each of two ring atoms of an arene
. The name for specific compounds requires the numerical prefix di-. E.g. 1,8-didehydronaphthalene or naphthalene-1,8-diyl.
1,2-Didehydroarenes are called arynes
and are commonly represented with a formal triple bond.
