Selective synthesis of dibenzo[a,c]cyclooctatetraenes via palladium-catalyzed [4+4] cyclic homocoupling of borylvinyl iodobenzene derivatives.
Dibenzo[a,c]cyclooctatetraenes were selectively generated in good yields from the palladium-catalyzed [4+4] cyclic homocoupling of borylvinyl iodobenzene derivatives, which were prepared via the selective Suzuki-Miyaura cross-coupling of the gem-diboryl reagents with iodo compounds.
