Ring currents in molecules with this property severely shield protons above and below them and deshield those in their plane.
This property has been been observed in a four aluminum atom cluster compound and a tritungsten nonoxide anion. This property may be quantified as the diamagnetic susceptibility exaltation, symbolized capital lambda. One molecule with this property is formed in the Elbs reaction. One family of reactions with these molecules sees them form allylic cations called Wheland intermediates. Ring currents in molecules with this property severely shield protons above and below them and deshield those in their plane. The energy owing to this property is named for Dewar, and a form of this property, exhibited by barrelene, was first demonstrated by Herges.. For 10 points, name this property of molecules that have continuous cyclic systems of sp2 hybridized atoms, which generally have 4n+2 pi electrons in those systems, an especially strong resonance stabilization..
