Abstract

The use of a tetraethylammonium halide in the presences of [Et2NSF2]BF4 (XtalFluor-E) enables efficient chlorination and bromination reactions of a wide range of alcohols. Iodination reactions are also possible albeit in lower yields. As opposed to Appel reactions, water-soluble side products are generated, that facilitate work-up.
