Enantioselective synthesis of sulfondiimidoyl fluorides via pyridine- N -oxide-catalyzed sulfondiimidoyl transfer

A catalytic asymmetric synthesis of sulfondiimidoyl fluorides is achieved via pyridine- N -oxide-catalyzed sulfondiimidoyl transfer. This process starts from in situ generated racemic sulfondiimidoyl chlorides, with enantioselective Cl–F exchange.
