Three‐Component Radical Cascade Reaction of Quinoxalinones, Alkenes and AgSCF3

Abstract A convenient and practical protocol for the preparation of SCF 3 ‐containing quinoxalin‐2(1 H )‐one derivatives via K 2 S 2 O 8 mediated difunctionalization of alkenes with quinoxalinones and AgSCF 3 was developed. The preliminary study showed that a SCF 3 radical triggered cascade reaction process might be involved in the current transformation.
