A mild and efficient Ru-catalyzed ortho-oxidative alkenylation of 2-arylbenzo[d]thiazoles through twofold C-H bond functionalization in aqueous solution of anionic surfactant sodium dodecylbenzenesulfonate (SDBS) has been developed using activated olefins as coupling partner. The protocol could be carried out smoothly on a gram scale, recyclable, and applicable to 2-arylthiazoles.
通过使用活化烯烃作为偶联伙伴,在阴离子表面活性剂十二烷基苯磺酸钠(SDBS)的水溶液中通过两倍的CH键官能化,温和有效地Ru催化了2-芳基苯并[ d ]噻唑的Ru催化正氧化烯基化。该方案可以以克为单位平稳地进行,可回收并适用于2-芳基噻唑。
