Nontransition metal-catalyzed synthesis of 2-aryl benzothiazoles was achieved through K2S2O8-mediated oxidative condensation of benzothiazoles with arylaldehydes. The same transformation can also be effected when the arylaldehydes were replaced with phenylglyoxylic acids.
通过K 2 S 2 O 8介导的苯并噻唑与芳基醛的氧化缩合反应,可以实现2-芳基苯并噻唑的非过渡金属催化合成。当芳基醛被苯基乙醛酸代替时,也可以实现相同的转化。

Abstract A simple, convenient, and efficientnew method for synthesis of 2-aryl benzothiazoles under mild conditions with nonmetal catalyst has been developed. Boron–dipyrromethene (BODIPY) dyes were used as photocatalysts for aerobic oxidative reactions of amine with 2-aminothiophenol. The approach will be very useful for the synthesis of benzothiazolederivatives and the development of photocatalytic
