A g-C3N4-based heterogeneous photocatalyst for visible light mediated aerobic benzylic C–H oxygenations

A visible light mediated metal-free heterogeneous photocatalytic system has been developed for highly efficient benzylic C–H oxygenations utilizing graphitic carbon nitride (g-C₃N₄) as a recyclable, nontoxic and low cost photocatalyst.
