## Abstract Sulfonation of norbornene 1 with the SO~3~βdioxane complex affords the Ξ²βsultone 2, which rearranges at room temperature to the Ξ³βsultone 3. Reaction of 1 with 2 equiv of SO~3~βnitromethane yields the carbyl sulfate 4. Carbocations are __not__ involved in the formation of either the Ξ²βs
