The coupling of sulfoximines 1 with various aryl bromides of different substitution pattern in the presence of a catalytic amount of Pd(OAc)2 and a chelating bisphosphine affords N-arylated products 3 with yields of up to 96%.

Various N-arylated sulfoximines have been synthesized in high yield by a direct approach which is based on a palladium-catalyzedcross-coupling strategy. Arylbromides of variable substitution pattern were found to be the most effective coupling partners, whereas aryliodides showed a nonpredictable behavior requiring lithium or silver salts as additives to ensure product formation in acceptable yields
