  Rh-Catalyzed C–H Amidation of 2-Arylbenzo[d]thiazoles: An Approach to Single Organic Molecule White Light Emitters in the Solid State

  摘要：

  A Rh-catalyzed direct C-H amidation of 2-arylbenzo[d]thiazoles has been developed. The transformation is characterized by its efficiency, external oxidant-free conditions, and the avoidance of a traditional three-step process consisting of nitration, ammoniation, and amidation. Furthermore, several of the prepared molecules exhibit bright white-light emission in the solid state.

  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。

  Selective construction of 2-substituted benzothiazoles from o-iodoaniline derivatives S8 and N-tosylhydrazone via a copper-promoted [3 + 1 + 1]-type cyclization reaction has been realized. In the protocol, the carbon atom on N-tosylhydrazone could be regulated to construct benzothiazole by changing the reaction system. Furthermore, the transformation has achieved the construction of multiple carbon-heteroatom

  benzothiazole derivatives in high yields was provided via copper catalyzed tandem cyclization with o-haloanilines, elemental sulfur and terminal alkynes as raw materials. In this protocol, C atoms on the CC triple bond were controllably involved in the construction of the benzothiazole framework and multiple carbon–heteroatom bonds through divergent routes.

  This reaction induces the cyclization of thiobenzanilides to benzothiazoles. The substrate absorbs visible light, and its excited state undergoes a reverse hydrogen-atom transfer (RHAT) with 2,2,6,6-tetramethylpiperidine N-oxyl to form a sulfur radical. The addition of the sulfur radical to the benzene ring gives an aryl radical, which then rearomatizes to benzothiazole via RHAT.
