Abstract
In this study, we explored the use of Mes-Acr-MeClO4 as a visible light photocatalyst for multicomponent reactions involving quinoxalin-2(1H)-ones with CBrCl3 and styrene. The method showcases regioselective functionalization of quinoxalin-2(1H)-ones in a three-component system, forming two C─C bonds in one pot. Mechanistic investigations suggest a radical-mediated pathway, initiated by the photoexcitation of Mes-Acr-MeClO4, followed by halogen atom abstraction from CBrCl3. This approach provides a versatile and sustainable route for quinoxalin-2(1H)-one functionalization, with Mes-Acr-MeClO4 effectively facilitating the photocatalyzed multicomponent reaction under mild conditions and visible light irradiation, yielding high selectivity and efficiency.
