A novel and efficient palladium-catalyzed dehydrogenative aminohalogenation of alkenes with molecularoxygen as the sole oxidant has been developed. This protocol provides a valuable synthetic tool for the assembly of a wide range of brominated enamines under mild conditions, with unprecedented stereoselectivity and exceptional functional group tolerance. This attractive route for the synthesis of
Stereoselective palladium-catalyzedoxidative C–N bond couplingreactions between aromatic amines and alkenes involving a solvent-controlled regioselective bromination process under 1 atm of oxygenatmosphere are disclosed, providing easy access to two different brominated enamines. The addition of hydrogen peroxide (30% aq) as a co-oxidant in the system is crucial for the dehydrogenative aminohalogenation
