A phosgene‐ and metal‐free synthesis of O‐aryl carbamates is realized through a three‐component coupling of carbon dioxide, amines and diaryliodonium salts. The reaction only requires a base as the promoter, providing access to a diverse array of O‐aryl carbamates in moderate to high yields with excellent chemoselectivity.
