An increasing number of enzymes are being discovered that contain radicals or catalyze reactions via radical intermediates. These radical enzymes are able to open reaction pathways that two‐electron steps cannot achieve. Recently, organic chemists started to apply related radical chemistry for synthetic purposes, whereby an electron energized by light is recycled in every turnover. This Minireview compares this new type of reaction with enzymes that use recycling radicals and single electrons as cofactors.
