An aerobic visible-light driven photoredox catalytic formation of 2-substituted benzothiazoles through radical cyclization of thioanilides has been accomplished. The reaction features C-H functionalization and C-S bond formation with no direct metal involvement except the sensitizer. The reaction highlights the following: (1) visible-light is the reaction driving force; (2) molecular oxygen is the terminal oxidant, and (3) water is the only byproduct.
通过硫代酰胺的自由基环化反应，实现了有氧可见光驱动的光氧化还原催化 2-取代苯并噻唑的形成。该反应的特点是 C-H 官能化和 C-S 键形成，除了敏化剂外，没有直接的金属参与。该反应具有以下特点：（1）可见光为反应驱动力；（2）分子氧为末端氧化剂；（3）水是唯一的副产物。
