The reactivity of methyl methanesulfonate in reaction with sulfur trioxide is lower than that of methyl arenesulfonates.Methyl methanesulfonate becomes exhausted when the ester and sulfur trioxide are in ratio of 1.85:1, while methyl p-toluenesulfonate becomes exhausted in ratio of 1:1 (25 deg C, 1 h).If an equimolar amount of chlorobenzene is added to the mixture of methyl methanesulfonate and sulfur trioxide in ratio of 1:1, the main reaction path is solvolysis of the pyrosulfonates to methanesulfonic acid and methylsulfuric acid and not the formation of sulfones, as in case of arenesulfonic esters.
