Halonium Catalysis: An Underutilized and Underexplored Catalytic Concept in Olefin Functionalizations.

Iodonium catalysis is described here to accomplish an intermolecular olefin oxyamination reaction. Urea is used as the O- and N-source to add across both activated and unactivated alkenes in a regioselective manner. Mechanistic studies confirm the presence of an iodonium intermediate.
