"The multicenter bond indices, recently proposed as quantitative measures of the cyclic delocalization in aromatic systems, have been applied to characterize the differences in the nature of the electron reorganization in a series of allowed and forbidden electrocyclic reactions of linear neutral polyenes of general formula CnHn+2 and related charged systems of formula CnHn+2(+) and CnHn+2(-) for n ranging from 4 to 7. The proposed methodology, which is based on the monitoring of the variation of the extent of cyclic delocalization along the concerted reaction paths, is shown to be completely consistent with the empirical Evans/Dewar classification anticipating aromatic transition states for allowed and antiaromatic transition states for forbidden electrocyclic reactions."@en .
