Chrysene and its bisbenzannulated homologue, naphtho[2,3-c]tetraphene, were synthesized through a PtCl2-catalyzed cyclization of alkynes, which also furnished corresponding biaryls subsequent to a Glaser coupling reaction of the starting alkynes. The optoelectronic properties of 5,5′-bichrysenyl and 6,6′-binaphtho[2,3-c]tetraphene were compared to their chrysene-based “monomers”. Oxidative cyclodehydrogenations of bichrysenyl and its higher homologue towards large nanographenes were also investigated.

New, efficient syntheses of chrysene (1), dibenzochrysene (16), and derivatives are described that feature, as the key step, the formal cycloaddition between 1,5-naphthodiyne (3) and a heterocyclic diene (furan, pyrroles, isoindoles).Subsequent manipulation affords the arene in 26-49percent overall yield from commercially available 2,6-dibromo-1,5-dihydroxynaphthalene (5).The latter is easily converted to ditosylate 6, which, with phenyllithium, serves as a synthon for 3.
