Spiroaromaticity

Spiroaromaticity in organic chemistry refers to a special case of aromaticity in which conjugation is interrupted by a single spiroatom. Although this spiro center disrupts the continuous overlap of p-orbitals, traditionally thought to be a requirement for aromaticity, considerable thermodynamic stability and many of the spectroscopic, magnetic, and chemical properties associated with aromatic compounds are still observed for such compounds.
