Abstract

The rate of alkaline hydrolysis of a substituted -sultam shows a dominant term second-order in hydroxide ion, clearly indicating the reversible formation of a monoanionic trigonal bipyramidal intermediate; substituent effects and kinetic parameters for the acid catalysed hydrolysis are indicative of the formation of a sulfonylium ion intermediate.
