Palladium-catalyzed double-Suzuki–Miyaura couplings between cyclic dibenziodoniums and arylboronic acids have been developed. As such, a wide range of o-tetraaryls 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.
