Benzylic Hydroperoxidation via Visible-Light-Induced Csp-H Activation.

A highly efficient benzylic hydroperoxidation has been realized through a visible-light-induced Csp-H activation. We believe that this reaction undergoes a direct HAT mechanism catalyzed by eosin Y. This approach features the use of a metal-free catalyst (eosin Y), an energy-economical light source (blue LED), and a sustainable oxidant (molecular oxygen).
