Abstract
Visible light-driven single-electron transfer-based direct cyanation of benzylic C-H bond with non-toxic N-Cyano-N-phenyl-p-toluenesulfonamide (NCTS) has been proposed using 4CzIPN, a widely used and affordable substitute for metal catalysts. The aforementioned method offers broad functional group tolerance, extensive substrate scope, excellent yields, and mild reaction conditions. This green and sustainable photocatalytic hydrogen atom transfer method can be applicable for the diversified functionalization of a variety of native C–H bonds.
