✦ Synopsis

The kinetics of the reaction of four X-3-(p-tolylsulfonyl)-1,2,3-benzoxathiazole 2,2-dioxides (X = 5-Cl, 5-Br, 5-NO 2 and 6-NO 2 ) with hydroxide ion and imidazole in aqueous acetonitrile and aqueous ethanol solutions were investigated at various pressures. The volumes of activation were all found to be negative and consistent with a bimolecular reaction involving considerable solvent electrostriction. No significant dependence on the solvent composition was found.

## Abstract The title compound **1** is a further example of an olefinic alcohol that undergoes ether formation under basic conditions **(β†’ 3)** although the double bond is not activated by an electron‐attracting group. This unusual reactivity is due to steric compression, which is increased in the
