Sulfoximidoyl-Containing Hypervalent Iodine(III) Reagents: 1-Sulfoximidoyl-1,2-benziodoxoles

Treatment of NH-sulfoximines with pseudocyclic benziodoxole triflate results in N–I bond formation leading to a new type of sulfoximidoyl-containing hypervalent iodine(III) reagents in high yields. Degradation studies revealed a pronounced stability in both the solid state and in solution.
