A visible light mediated metal-free heterogeneous photocatalytic system has been developed for highly efficient benzylic C–H oxygenations utilizing graphitic carbon nitride (g-C ₃ N ₄ ) as a recyclable, nontoxic and low cost photocatalyst.

An efficient and eco-friendly heterogeneous photocatalytic protocol for the synthesis of fluoroalkyl-containing compounds via the fluoroalkylation-distal functionalization of alkenes with R_FSO₂Na under air atomosphere is reported.

A Cu-doped carbon nitride-based heterogeneous metallaphotocatalytic α-alkynylation of tertiary amines has been developed, allowing for green and sustainable synthesis of diverse valuable propargylamines with high efficiency.
