The cyclodehydration of bis(pyridiniummethyl)methylbenzenes 3a-b in polyphosphoric acid leads to methyl-substituted diazoniapentaphene salts 4a-b instead of linear diazoniapentacene derivatives, while the 1,3-bis(pyridinium- methyl)bromobenzene 3d forms a

"Photochemical synthesis of polycyclic aromatic hydrocarbons and NMR-1H study of bay protons.Specific solvent effects and nuclear Overhauser effects".Dinaphthoanthracene (4a),9-bromo-dinaphthoanthracene (4b), 9-methyldinaphthoanthracene (4c), benzonaphthochrysene (7), benzonaphthoanthracene (3), naphthochrysene (9) and dibenzonaphthochrysene (12) have been synthesized by the photocyclodehydrogenation of 1,2-diarylethylenes (5,8) and bis (arylvinyl)arenes (6,10).The NMR study has been mainly focused on the bay protons involved in specific solvent effects Table 4) and nuclear Overhauser effects (Table 5).
