Product Introduction:

A method for preparing substituted benzenesulfonamide or benzenesulfonamide compounds under neutral to weak alkaline or acidic conditions in an aqueous system. The present invention is characterized in that: 1) the reaction system is maintained under neutral to weak alkaline conditions in an aqueous phase system, which can avoid the hydrolysis of sulfonyl chloride due to the system being too alkaline or the inhibition of the reaction in an acidic system to improve the amine substitution rate; Or 2) Prolonging the reaction time under acidic conditions can also improve the amine substitution rate. The amine substitution rate can be controlled within the range of 1% -99%.
