Antimony pentachloride reaction with alkenes

When terf-pentyl alcohol was reacted with acetic anhydride and perchloric or tetrafluoroboric acids, the reaction proceeded via the more stable trisubstituted alkene (21) under thermodynamic control and the reaction product was mainly a 2,3,4,6-tetramethylpyrylium salt (25). However, with terf-pentyl chloride, acetyl chloride and aluminum chloride or antimony pentachloride, the diacetylation occurred under kinetic control the alkene equilibration proceeds very fast with these Lewis acids so that the product (26) is derived from the more reaetive but less stable disubstituted alkene (22) 63,64 formulas below, the intermediate monoaeetylation products... [Pg.410]
