A new class of chiral electrophilic thiocyanating reagents was designed and synthesized through an efficient protocol. These bench-stable and robust reagents were applied for the functionalization of electron-rich (hetero)arenes and the difunctionalization of alkenes.

A convenient method to introduce a thiocyano group into an olefin with thallium triacetate is described. The reaction proceeds via oxythallation, replacement of an acetate ion with a thiocyanate ion, and dethallation, successively.
