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

between the desulfurization of the corresponding substrates via a hydrodesulfurization (HDS) or by a hydrodesulfurative cross-coupling (HDSCC) reaction. Furthermore, in the absence of water sulfur-free poly-phenylic compounds were obtained in good yields as a result of a Suzuki–Miyaura type reaction, being the main product in most of the cases the corresponding o-terphenyl derivative, these products are
