The acid-catalyzed hydrolysis of -sultams is strongly retarded by electron-withdrawing groups to the sulfonyl group, and it is suggested that the mechanism may involve unimolecular ringopening to generate a sulfonylium ion. The Brnsted lg value for the acid-catalyzed hydrolysis of N-benzyl--sultams is 0.32. The general-acid-catalyzed hydrolysis of N-benzyl--sultam by carboxylic acids shows a Brnsted
