Definition of dehydroarenes

1. 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. RNRI Rule RC-81.3.1.

   1,2-Didehydroarenes are called arynes and are commonly represented with a formal triple bond.
