A direct Fe-catalyzed synthesis of β-alkyl N-aryl aza Baylis-Hillman (ABH) adducts involves the formation of a C-N bond via a nitroso-ene reaction. This is a simple, fast, and best alternate method to overcome the substrate scope limitations of the ABH reaction. Various arylhydroxylamines reacted with esters, aldehydes, ketone, and nitriles to yield the corresponding products in good yields.
