A catalytic benzylic Csp3–H functionalization protocol is described here. This visible light-mediated process is centered on the utilization of a bromide catalyst and oxidant to generate a nitrogen (N)-centered radical...

A hypervalent iodine-catalyzed conjugate addition with a sulfonamide nucleophile is described here. This reaction utilizes catalytic amounts of iodoarene and oxidant for the generation of the active hypervalent iodine catalyst. Activation of the enone substrate by the hypervalent iodine catalyst enables the nitrogen nucleophile addition that eventually forms a useful -aminocarbonyl product. This hypervalent iodinecatalyzed Aza-Michael reaction represents an interesting alternative to existing conjugate addition protocols.

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 un-activated alkenes in a regioselective manner. Mechanistic studies confirm the presence of an iodonium intermediate.
