Copper-Mediated Cross-Coupling Reactions of N-Unsubstituted Sulfoximines
and Aryl Halides. — A ligand-free copper-mediated title reactions for the synthesis of
various N-arylated sulfoximines in high yields is reported. Shorter reaction times,
higher reactivity, and economical practicality are advantages of the methodology compared to the previously used palladium- mediated protocol. In the reaction of (S)—(I)
with (XIX) both methods are affording different products, i.e. (XX) and (XXI). The
novel methology allows the access to various compounds not available so far. —
