Synthesis of 3-CF(2)-Containing Chromones via a Visible-Light-Induced Radical Cascade Reaction of o-Hydroxyaryl Enaminones

[Image: see text] A general and efficient visible-light-induced CF(2) radical-based cascade reaction of o-hydroxyaryl enaminones has been described. This protocol afforded the corresponding functionalized 3-CF(2)-containing chromones in generally good yields under mild reaction conditions. The use o...
