Re: Stability of Antiaromatic vs Nonaromatic Molecules « Reply #1 on: July 09, 2014, 02:03:05 PM » When its 4n (antiaromatic), the energy levels can be degenerate, but the charge is delocalized differently. For example, antiaromatic compounds between magnets are paramagnetic; aromatic...
Antiaromatic or Nonaromatic? 2 1 H ,6 1 H -2,6(2,5)-Dipyrrola-1,5(2,6)-dipyridinacyclooctaphane-3,7-diene: a Porphycene Derivative with 4 N π Electrons A porphycene-derived compound with a 20 蟺-electron skeleton has been obtained by replacing two pyrrolene units of porphycene...
electrons conjugation, and we get to see fully filled orbits as compared to antiaromatic compounds with just (4n) π electrons. this makes the compound very reactive. apart from this, aromatic compound are differentiated from similar nonaromatic compounds by the level of susceptibility. the ...
A high negative NICS(0) indicates aromatic character of the system, whereas a small negative or a positive NICS(0) reveals non-aromatic or antiaromatic character respectively. After proposing this index as a possible indicator of aromaticity, there have been successive refinements [33]. It was ...
