Abstract: A novel and efficient palladium-catalyzed dehydrogenative aminohalogenation of alkenes with molecular oxygen 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 brominated enamines is of great significance due to the products versatile reactivity for further transformations.This work was published in J. Am. Chem. Soc. 2013, 135, 5286.
Key Words: Molecular oxygen; Palladium-catalyzed; Brominated enamines
