Abstract

The Migita–Kosugi–Stille coupling reaction is a powerful method for the formation of carbon–carbon bonds but often requires high temperatures that are not tolerated by all substrates. Herein, we report that irradiation with UV light accelerates this coupling reaction at room temperature in air in the presence of the commercially available PdCl2(PPh3)2 catalyst. This UV-light-assisted coupling reaction requires the presence of molecular oxygen, with mechanistic studies revealing that singlet oxygen is most likely involved in the reaction.
