Cu(OAc)2-catalyzed N-arylations of sulfoximines with aryl boronic acids.
[reaction: see text] A simple and mild copper salt-catalyzed N-arylation of sulfoximines in high yields is reported. Cu(OAc)(2) activates aryl boronic acids for the reaction with NH-sulfoximines without additional base or heating. Furthermore, this new method allows the preparation of N-arylated sulfoximines, which have previously been more difficult to access.
