Highly Selective Activation of Vinyl C-S Bonds Over Aryl C-S Bonds in the Pd-Catalyzed Coupling of (E)-(beta-Trifluoromethyl)vinyldiphenylsulfonium Salts: Preparation of Trifluoromethylated Alkenes and Dienes

[摘要]：We describe the Suzuki coupling reaction of (E)-(beta-trifluoromethyl)vinyldiphenylsulfonium salts with arylboronic acid. The highly efficient and selective reaction provides a useful and mild method for the synthesis of trifluoromethylated alkenes and dienes. Subsequent DFT studies showed that the oxidative addition transition state of the vinyl CS bond is much more favorable (11.7 kcal?mol1) than that of the aryl CS bond.
