Treatment of N-methyl-S,S-diaryl sulfoximines with methyl trifluoromethanesulfonate provides bench-stable sulfoxinium salts in excellent yields. Applying them in Sonogashira-, Heck- and Suzuki-type cross-coupling reactions leads to the corresponding products by sequential C–S bond cleavage and C–C bond formation. Electronic factors induced by substituents on the S-aryl groups govern the coupling efficiency.
