An efficient methodology for the functionalization of sp³ C–H bond adjacent to nitrogen has been developed utilizing visible light-induced photoredox catalysis. Through optimization of solvent and light source, the reaction can be rapidly achieved to provide the desired product under mild reaction conditions.

A visible-light-enabled, iron-catalyzed three-component reaction for difunctionalization of alkenes with amines and diselenides has been developed, wherein a photo-excitable Fe-amine complex is proposed as the key intermediate.

A decarboxylative ring-opening reaction of cyclic tertiary carboxylic acidsviaan iron-catalyzed photoinduced ligand-to-metal charge transfer (LMCT) process is herein reported.
