Abstract

3, 8-Diphenylpyrene 5 and 3, 10-diphenylpyrene 10 were synthesized from 1, 5- dibenzylnaphthalene and 1, 4-diphenylnaphthalene. Dibenzylnaphthalenes were dehydrogenated to the quinonoid compounds 2 and 7, followed by addition of maleic anhydride and dehydrogenation of the adducts to give the aromatic anhydrides 4 and 9. These were decarboxylated to the corresponding hydrocarbons. By an analogous ...
