The metal‐free amination of different aldehydes is catalyzed by hypoiodite, which is generated by employing commercially available sodium percarbonate as the co‐oxidant. This approach has several advantages: it is a metal‐free oxidation that works under mild reaction conditions; furthermore, it has a wide substrate scope and does not give toxic by‐products from the co‐oxidant that is used.
