A highly efficient protocol for regioselective ring-opening of epoxides with alcohols,water, acetic acid,and acetic anhydride catalyzed by SbF3

SbF₃ as an efficient catalyst has been used for regioselective alcoholysis, acetolysis and hydrolysis of epoxides to the corresponding β-alkoxy, β-acetoxy alcohols, and 1,2-diols in high to excellent yields. This study also represents a convenient synthesis of vic-diacetates from ring-opening of epoxides with acetic anhydride.
