Catalytic Coupling of Aryl Sulfonates with sp2-Hybridized Nitrogen Nucleophiles: Palladium- and Nickel-catalyzed Synthesis of N-Aryl Sulfoximines

Abstract

Several sulfoximines have been arylated in good to high yield by palladium catalysis using aryl nonaflates and aryl triflates. Moreover, the successful synthesis of N-aryl sulfoximines from aryl tosylates is described using a Ni(COD)2/BINAP catalyst.
