Abstract

The application of set of homodesmotic reactions allowed us to estimate the aromatic stabilization energy (ASE) of corannulene and coronene. Appropriate reactions have been applied to balance syn/anti mismatches in di-, tetra- and hexamethylene substituted derivatives. Based on many different polycyclic reference structures that compensate the effect of strain in the corannulene moiety the value of ASE comes to 44.5 kcal mol−1. Planar corannulene is more stabilized by cyclic π-electron delocalization by ca. 10.7 kcal mol−1, as compared with a bowl-shaped system. A similar approach for coronene leads to an ASE equal to 58.4 kcal mol−1.
