Cobalt-Catalyzed Regioselective C8–H Sulfoxamination of 1-Naphthylamine Derivatives with NH-Sulfoximines

A simple cobalt-catalyzed, picolinamide-directed C8–H sulfoxamination of 1-naphthalamides with NH-sulfoximines has been developed. This cross-dehydrogenative C–H/N–H coupling reaction offers a facile route to N-arylated sulfoximines, exhibiting high yields, a broad substrate scope, and excellent functional group tolerance and scalability.
