for the selective S-alkylation of sulfenamides under basic conditions to yield sulfilimines. The key step involves the resonance between bivalent nitrogen-centered anions, generated after deprotonation of sulfenamides under alkaline conditions, and sulfinimidoyl anions. Our sustainable and efficient approach employs sulfur-selective alkylation of readily accessible sulfenamides and commercially available
