A new and general method to functionalize the C(sp3)–C(sp2) bond of alkyl and alkene linkages has been developed, leading to the dealkenylative generation of carbon-centered radicals that can be intercepted to undergo Ni-catalyzed C(sp3)–C(sp2) cross-coupling. This one-pot protocol leverages the easily procured alkene feedstocks for organic synthesis with excellent functional group compatibility without

A series of new bowl‐shaped N‐hydroxyimide derivatives has been designed and used as selective organoradical catalysts. A number of these bowl‐shaped N‐hydroxyimide derivatives exhibit excellent site‐selectivity in the amination of benzylic C(sp3)−H bonds in aromatic hydrocarbon substrates.
