Synthesis of Bis(diaryl)sulfones by Site-Selective Suzuki-Miyaura Reactions of 2,4 '-Bis(trifluoromethylsulfonyloxy)diphenylsulfone

[摘要]：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'.
