Well‐defined hypervalent iodine(III) reagents incorporating transferable sulfoximidoyl groups were obtained through ligand exchange reactions of methoxy(tosyloxy)iodobenzene (MTIB) with NH sulfoximines in good to excellent yields. The solid‐state structure of a representative product was characterized by X‐ray crystallography. Utilizing these reagents in synthesis provides a new, transition‐metal‐free approach towards N‐alkynylated sulfoximines.
