Reactions of ω-phenylalkenes 1a-31a with sulfur trioxide were studied in the temperature range -60 to 25 deg C using dichloromethane as solvent and 1.5 mol equiv. of dioxane as reactivity moderator. ω-Phenylalkenes 1a-7a react just like simple alkenes: at
REACTIONS OF ALKENES AND Ω-PHENYLALKENES WITH SULFUR TRIOXIDE; SULFONATION AND FRIEDEL-CRAFTS TYPE OF CYCLIZATION

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.
