Key Points

  • The aerboic photochemical oxidation of boronic acids occurs efficiently with a dibenzothioxanthene imide as photocatalyst.
  • Using just 0.01% catalyst loading and irradiation at 456 nm proves the method's efficiency and sustainability.
  • Success across various substrates shows that the visible light-promoted method has broad application potential.
  • This approach highlights a greener alternative for chemical synthesis in organic chemistry.

Abstract

Herein, a sustainable and eco‐friendly protocol is reported for the aerobic photochemical oxidation of boronic acids or esters, utilizing a dibenzothioxanthene imide as the photocatalyst at a very low catalyst loading (0.01%) in 2‐propanol, employing a 456 nm irradiation source. Additionally, this protocol is successfully applied to a variety of substrates.
