A direct catalytic imidation of sulfides to sulfimides with [N-(p-tolylsulfonyl) imino] phenyliodinane (TsN IPh) using a catalytic amount of copper triflate (CuOTf) has been developed. The reaction proceeds with a wide range of sulfides to give the corresponding sulfimides in 50-83% isolated yields. When the reaction is applied to allylic sulfides, the products are the corresponding sulfonamides produced via [2, 3] sigmatropic ...
