The known reagent O‐mesitylenesulfonylhydroxylamine (MSH) led to regioselective thioethercleavage, but a large excess of reagent was needed, thus making purification challenging. An unexpected side reaction observed during the investigation of the base‐induced elimination inspired us to develop a new thioether‐cleavage methodology based on the addition of propargylamine as a nucleophile that can trap
