https://doi.org/10.1351/goldbook.D01574

Definition:
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. D01574.png 1,2-Didehydroarenes are called arynes and are commonly represented with a formal triple bond.
