Visible-light-induced three-component reaction of quinoxalin-2(1H)-ones, alkenes and CF3SO2Na leading to 3-trifluoroalkylated quinoxalin-2(1H)-ones
2020
Abstract A facile and metal-free visible-light-enabled three-component reaction of quinoxalin-2(1H)-ones, alkenes and CF3SO2Na has been developed under air at room temperature. This photocatalytic tandem reaction using 4CzIPN as the photocatalyst and air as the green oxidant, provides a mild and environmentally friendly approach to access a series of 3-trifluoroalkylated quinoxalin-2(1H)-ones.
