Benzene and pyrene can be synthetically linked to [o-COSAN](-) while maintaining their aromaticity, while naphthalene and anthracene are extruded in the same reaction. The number of Clar's pi-sextets determines whether extrusion is favorable or not. Thus, Clar provides the answer to the extrusion of attached polycyclic aromatic hydrocarbons to [o-COSAN](-).
Benzene and pyrene can be synthetically linked to [o-COSAN](-) keeping their aromaticity. In contrast, naphthalene and anthracene are extruded in the same reaction. We have proven that extrusion is only favorable if the number of Clar's pi-sextets remains constant. Thus, Clar has the answer to whether an attached polycyclic aromatic hydrocarbon to [o-COSAN](-) is extruded or not.
