The Suzuki-Miyaura reaction of the bis(triflate) of 2,4′-bis(hydroxy)diphenylsulfone with two equivalents of boronic acids gave 2,4′-bis(aryl)diphenylsulfones. The reaction with one equivalent of arylboronic acids resulted in site-selective attack onto carbon atom C-4′.
2,4'-双(羟基)二苯基磺酮的双(triflate)与两个当量的硼酸反应生成了2,4'-双(芳基)二苯基磺酮。与一个当量的芳基硼酸反应则导致对C-4'碳原子的位点选择性攻击。
