Table 2. N-Allylsulfonamide Scope^a.

^aReaction conditions: 0.2 mmol, 1.0 equiv of N-allyltoluenesulfonamide, 1.5 equiv of 1,3-dichloro-5,5′-dimethylhydantoin, 3.0 equiv of methylenecyclohexane, 0.5 mol % (Ir[dF(CF₃)ppy]₂(dtbpy))PF₆, 4 mL total (step 2) of DCM. ^a1.5 equiv of 1,3-dibromo-5,5′-dimethylhydantoin was used instead of 1,3-dichloro-5,5′-dimethylhydantoin.

^b1.5 equiv of 1,3-diiodo-5,5′-dimethylhydantoin was used instead of 1,3-dichloro-5,5′-dimethylhydantoin.

^cStarting material 1l was the sole observed product in the crude ¹H NMR spectrum.
