Abstract Owing to its possible advantages for the environment and economy, photoredox catalysis of organic processes fueled by iron has garnered a lot interest recently. The potential photo‐induced single‐electron transfer (SET) events occurring outside sphere is now well acknowledged. Currently, focus shifted newly discovered photoactivation method that based on an inner‐sphere mode reactivity caused population visible‐light‐induced homolysis (VLIH) states. VLIH activation, in contrast photoredox, specific complexes, offers distinct profiles, does not require redox potentials coincide. These attractive properties have prompted development strategies use this blueprint manufacture highly reactive open‐shell species mild environments. purpose contribution promote novel synthetic techniques sustainable chemical transformations offer educational instrument understanding evolving idea.
