An efficient B(C6F5)3-catalyzed aerobic oxidative C–S cross-coupling reaction of thiophenol with indoles was developed, affording a wide range of diaryl sulfides in good yields. An electron donor–acceptor complex between B(C6F5)3 and indoles was formed, facilitating the photoinduced single-electron transfer (SET) from indole substrates to the B(C6F5)3 catalyst. This protocol demonstrates a new reaction model using B(C6F5)3 as a single-electron oxidant.

B(C6F5)3-催化电子供体-受体复合物介导的吲哚在可见光条件下的有氧磺化

开发了一种高效的 B(C 6 F 5 ) 3催化的苯硫酚与吲哚的有氧氧化 C-S 交叉偶联反应,以良好的收率提供了范围广泛的二芳基硫化物。B(C 6 F 5 ) 3和吲哚之间形成了电子供体-受体复合物,促进了从吲哚底物到B(C 6 F 5 ) 3催化剂的光诱导单电子转移(SET) 。该协议展示了使用 B(C 6 F 5 ) 3作为单电子氧化剂的新反应模型。
