Reactions of the ο-(1-naphthyl)-n-alkenes 1a-9a and 1,7-diphenyl-3-heptene (10) (substrates which allow intramolecular competition in any occurring sulfocyclization) with sulfur trioxide were studied in the temperature range -60 to 25 deg C using dichloro

Reaction of alkenes with SO3 leads to the formation of β-sultones, carbyl sulfates, alkenesulfonic acids and γ-sultones, depending on the alkene structure and on the reaction conditions.The high selectivity for the cyclisation to 1,2,3,4-tetrahydronaphthalene sulfonic acid derivatives on reaction of well chosen ω-phenylalkenes with SO3 infers the occurence of a relatively fast equilibrium between ω-phenyl-m,n- and the ω-phenyl-n,m-alkanesultone intermediate.
