Abstract: Two 1-substituted cis-1,2-cyclohexanediol monosulfonate acid amplifiers were prepared by hydrogen peroxide oxidizing of corresponding olefin and then esterified with p-toluenesulfonyl chloride. The acidolysis properties were studied directly by detecting the small amounts of acid generated by the compounds with our method using bromophenol as indicator. The two compounds displayed good acidolysis property when moderately warmed but the storage stability is low. They are also unstable to polar solvents.
