Abstract

We report a chemoselective Suzuki–Miyaura reaction protocol of using bromophenyl fluorosulfonate as building block for the preparation of unsymmetrical terphenyls. The chemoselective cross-coupling of bromophenyl fluorosulfonate and arylboronic acids can be achieved by controlling base species without using any ligands. Under this methodology, various of m- and p-unsymmetrical terphenyls were obtained in moderate to good yields.
