  2-Aryl benzothiazole formation from aryl ketones and 2-aminobenzenethiols under metal- and I2-free conditions was described. Various 2-aryl benzothiazoles were selectively obtained in good yields using molecular oxygen as oxidant. DMSO played an important role in this transformation. Functional groups such as methyl, methoxy, fluoro, chloro, bromo and nitro groups were tolerated under the optimized reaction

  A supported Ni(II) complex has been synthesized and characterized by FTIR, UV–vis diffuse reflectance spectroscopy, thermogravimetric analysis and scanning electron microscopy. Its catalytic activity was evaluated for alkyne–azide coupling and benzothiazole synthesis. These reactions were found to require mild conditions, reaction times, and most importantly, could be carried out in aqueous medium. The catalyst could be easily recovered and reused five times without significant decrease in its activity. Leaching tests indicated that the catalyst is truly heterogeneous. The nickel complex was tested for its inhibition of germination of MTU 7029 seeds. Rice (MTU 7029, Oryza sativa) is a staple crop in southeast Asia.

• Exogenous Photosensitizer-, Metal-, and Base-Free Visible-Light-Promoted C–H Thiolation via Reverse Hydrogen Atom Transfer

  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.

  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。
