Iron(II)-Catalyzed Direct Synthesis of NH Sulfoximines from Sulfoxides

Abstract

Free NH-sulfoximines were directly prepared from sulfoxides through iron catalysis by applying a readily available, shelf-stable hydroxylamine triflic acid salt. No additional oxidant is needed, and the substrate scope is broad, including a range of heterocyclic compounds.

Keywords: heterocycles; imidation; iron; sulfoxides; sulfoximines.
