title: Base-promoted coupling of carbon dioxide, amines, and diaryliodonium salts: a phosgene- and metal-free route to O-aryl carbamates.
abstract: 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.
