Benzocyclobutadiene
From Wikipedia, the free encyclopedia
Benzocyclobutadiene is the simplest polycyclic aromatic hydrocarbon, being composed of a benzene ring fused to a cyclobutene ring. It has chemical formula C8H6 and CAS number []. It is antiaromatic, because it has 2n pi electrons. For this reason the compound is very reactive. It will easily dimerize or polymerize and reacts as the dienophile in Diels-Alder reactions [1]
