摘要

Abstract A visible‐light‐induced Rose bengal catalyzed C3‐trifluoroethylation of quinoxalin‐2‐(1 H )‐ones is reported. A wide range of quinoxalin‐2‐(1 H )‐ones was compatible, which led to the corresponding products in moderate to good yields. A gram‐scale reaction proceeded well and afforded an efficient route to prepare C3‐trifluoroethylated quinoxalin‐2‐(1 H )‐ones.
