Rotational isomerism in the radical anions of bi- and ter-aryls containing the thiophen ring

Gian Franco Pedulli,   Marcello Tiecco,   Maurizio Guerra,   Giorgio Martelli  and  Paolo Zanirato  

Abstract

The conformational behaviour of the radical anions of several bi- and ter-aryls has been investigated by e.s.r. spectroscopy. Comparison with their diamagnetic precursors shows that the addition of the unpaired electron to the π-system greatly increases the conformational rigidity of these compounds. This result is accounted for by INDO MO calculations, and can be rationalized in terms of the occupancy by the unpaired electron of the lowest vacant orbital of neutral bi- and ter-aryls which has a strong bonding character in the interannular regions.
