CAPTURING ANTIAROMATICITY.Focuses on the ability of cyclooctetraene (COT), an organic cyclic compound to escape the consequences of antiaromaticity. Discussion on the 4n+2 rule for aromaticity; Stability of antiaromatic compound; Use of annelation to alter the nature of COT; Evidence of ...
π-Conjugated macrocycles behave differently from analogous linear chains because their electronic wavefunctions resemble a quantum particle on a ring, leading to aromaticity or anti-aromaticity. [18]Annulene, (CH)18, is the archetypal non-benzenoid arom
Nickel norcorrole provides an unusual example of a molecule that is strongly antiaromatic according to the magnetic criterion, but which exhibits, according to high-quality DFT calculations, a symmetric, delocalized structure with no difference in bond length between adjacent Cmeso-Cα bonds. A frag...
Classify the following molecules as aromatic and antiaromatic: Aromaticity: Aromaticity is a property which has planar, cyclic structure with a ring of resonance bonds that gives to increase the stability and obey huckel rules. Aromatic compound are those compounds which obeys huckel's rule (4n...
The exaltations (Λ) of the aromatic compounds are negative (diamagnetic), whereas for the antiaromatic systems, they are positive (paramagnetic) [7]. In accordance with the diagonality rule of the Periodic Table, phosphorus atom in the low coordination state (coordination Nos. 1 or 2) resemb...

Stability and Aromaticity of Charged Mobius[4n]Annulenes A number of parent aromatic Mbius annulenes that violate the H眉ckel rule have been proposed theoretically. Unfortunately, these species are thermodynamically and kinetically unstable and probably impossible to synthesize. We therefore s... EK ...
