Substitution of allylic sulphides of benzothiazole-2-thiol with organomagnesium compounds in the presence of copper(I) iodide. A regioselective synthesis of olefins
Abstract
Primary allylic sulphides of benzothiazole-2-thiol react with butylmagnesium bromide in the presence of copper(I) iodide to yield, depending on the solvent, olefins with or without allylic rearrangement.
