A novel three-component cascade radical reaction involving non-activated olefins, quinoxalin-2(1H)-ones, and AgSCF3 was proposed. Under the action of the oxidizing agent K2S2O8, 40 quinoxaline derivatives containing SCF3 were obtained with the highest yield of 78%. This method provides a mild and environmentally friendly approach to prepare trifluoromethylthio-substituted quinoxalines, offering advantages such as high yield, broad substrate scope, atom economy, and environmental efficiency.

Key words: (trifluoromethylthio) silver(I), radical, three-component reaction
