AI Article Synopsis

  • A novel technique for creating 3-arylindoles utilizes visible light with dual gold and photoredox catalysts.
  • This method boasts benefits like cascade catalysis, high efficiency, redox-neutral conditions, and the ability to tolerate various functional groups.
  • The process involves forming an electrophilic arylgold(iii) intermediate through photoredox promotion, which then couples with an arylamine nucleophile.

Article Abstract

A new method for the synthesis of 3-arylindoles has been developed by visible light mediated dual gold/photoredox catalysis. This transformation has many features such as cascade catalysis, high efficiency, redox-neutral reaction conditions and good functional group tolerance. The reaction proceeds through the photoredox-promoted formation of an electrophilic arylgold(iii) intermediate that undergoes coupling with the arylamine nucleophile.
