Palladium-Catalyzed Double-Suzuki-Miyaura Reactions Using Cyclic Dibenziodoniums: Synthesis of o-Tetraaryls

Palladium-catalyzed double-Suzuki-Miyaura couplings between cyclic dibenziodoniums and arylboronic acids have been developed. As such, a wide range of otetraaryls were synthesized in good to excellent yields of 22-94%. Furthermore, tetraphenylene was prepared in 21% isolated yield with 2,2'-biphenyldiboronic acid by using this method.
