Novel selenium containing non-detergent sulphobetaines

Abstract

The first selenium containing non-detergent sulphobetaines are described. They have been prepared in multi-gram quantities from readily available pyridyl precursors. Incorporation of selenium was achieved using nucleophilic organoselenide anions. The resulting products were shown by 77 Se NMR spectroscopy to be homogeneous with respect to selenium oxidation state. The first selenium containing non-detergent sulphobetaines are described.
