Cyclooctatetraene nonaromatic or antiaromatic

WebCyclooctatetraene is chlorinated to give a [4.2.0]- bicyclic compound, which reacts further with dimethyl acetylenedicarboxylate in a Diels-Alder reaction (DA). Retro-DA at 200 °C releases cis-dichlorocyclobutene. This compound reacts with diiron nonacarbonyl to give cyclobutadieneiron tricarbonyl.

WebCyclopentadiene is not anti-aromatic. It’s just a diene. There are three initial criteria that must be met before we consider electrons in the pi system. To be aromatic (Unusually stable) like cyclopentadienyl anion you must be planar : p orbitals parallel cyclic: a ring conjugated (having a p orbital at every atom in the annulene) WebBecause cyclooctatetraene is not flat nor conjugated it is properly defined as non-aromatic. In general, if an antiaromatic compound has the ability to form a non-planar shape it will do so to avoid destabilization by becoming non-aromatic. Determining if a Compound is Aromatic, Antiaromatic, or Nonaromatic WebAnnulenes may be aromatic (benzene, [6]annulene and [18]annulene), non-aromatic ( [8] and [10]annulene), or anti-aromatic (cyclobutadiene, [4]annulene). Cyclobutadiene is the only annulene with considerable antiaromaticity, since planarity is unavoidable. brs homemade fish food
