  外源光敏剂，无金属和无碱可见光通过逆向氢原子转移促进了C–H硫醇化

  摘要：

  无需添加光敏剂，金属催化剂或碱即可实现可见光驱动的分子内C（sp 2）–H硫醇化。该反应诱导了硫代苯甲酰胺环化为苯并噻唑。底物吸收可见光，并且其激发态与2,2,6,6-四甲基哌啶N-氧基发生反向氢原子转移（RHAT），形成硫自由基。硫自由基加到苯环上会得到一个芳基，然后再通过RHAT重新形成苯并噻唑。

  光催化氧化 C-H 硫醇化：苯并噻唑和磺化吲哚的合成

  摘要：

  我们报告了光催化形成 C-S 键以通过分子内环化形成苯并噻唑和通过分子间反应形成磺基化吲哚的研究。循环伏安法 (CV) 和密度泛函理论研究表明，苯并噻唑的形成通过涉及亲电硫自由基的机制进行，而吲哚磺基化可能通过亲核硫自由基加入自由基阳离子吲哚进行。这些条件已成功扩展到几种硫代苯甲酰胺和吲哚底物。

• External Oxidant-Free Oxidative Cross-Coupling: A Photoredox Cobalt-Catalyzed Aromatic C–H Thiolation for Constructing C–S Bonds

  An external oxidant-free oxidative coupling for aromatic C-H thiolation by visible-light photoredox cobalt-catalysis has been developed. Various substrates could afford benzothiazoles in good to excellent yields, and only H2 is generated as a side product. When catalytic TBAOH was used as the base, not only 2-aryl but also 2-alkylbenzothiazoles could be obtained through this novel dehydrogenative coupling reaction. This method could be scaled up and applied to the synthesis of biologically active molecules bearing benzothiazole structural scaffolds (potent antitumor agents). Furthermore, the unexpected oxidation byproduct amides, which are often generated in oxidative cyclization of thiobenzanilides, can be completely avoided. Mechanistic studies showed that the H2 originates from the substrates. The kinetic studies indicate that the interaction between the cobalt catalyst and proton might be involved in the rate-limiting process.
• Organocatalytic Syntheses of Benzoxazoles and Benzothiazoles using Aryl Iodide and Oxone via C–H Functionalization and C–O/S Bond Formation

  An organocatalytic protocol for the syntheses of 2-substituted benzoxazoles and benzothiazoles is described from alkyl-/arylanilides and alkyl-/arylthioanilides using 1-iodo-4-nitrobenzene as catalyst and oxone as an inexpensive and environmentally safe terminal oxidant at room temperature in air via oxidative C-H functionalization and C-O/S bond formation. The procedure is simple and general and provides an effective route for the construction of functionalized 2-alkyl-/arylbenzoxazoles and 2-alkyl-/arylbenzothiazoles with moderate to high yields. The synthetic and mechanistic aspects have been described.
