AI Article Synopsis
- A new method for trifluoromethylating quinoxalin-2(1)-ones was developed, using a Z-scheme VO/g-CN heterojunction as a photocatalyst, which works under mild, additive-free conditions at room temperature.
- This process efficiently produced various trifluoromethylated quinoxalin-2(1)-one derivatives with moderate to high yields, showing compatibility with different functional groups.
- The VO/g-CN photocatalyst was recyclable, maintaining its effectiveness over five uses with only a slight decrease in activity.
Article Abstract
A visible-light-initiated C-H trifluoromethylation of quinoxalin-2(1)-ones was established using a Z-scheme VO/g-CN heterojunction as a recyclable photocatalyst in an inert atmosphere at room temperature under additive-free and mild conditions. A variety of trifluoromethylated quinoxalin-2-(1)-one derivatives were heterogeneously generated in moderate to high yields, exhibiting good functional group tolerance. Remarkably, the recyclable VO/g-CN catalyst could be reused five times with a slight loss of catalytic activity.
