Two Catalytic Protocols for the Synthesis of N ‐Aryl Sulfoximines From Aryl Thianthrenium Salts

Two complementary catalytic strategies for the N ‐arylation of sulfoximines using bench‐stable aryl thianthrenium salts are reported. A Pd/RuPhos system efficiently promotes coupling under mild thermal conditions, while a visible‐light‐induced Ir/Cu dual‐catalytic system operates at room temperature via a radical pathway. Both methods are scalable, tolerate a wide range of functional groups, and provide practical access to N ‐aryl sulfoximines, highlighting the tunable reactivity of aryl thianthrenium salts in polar and radical manifolds.
