Evidence consistent with an elimination mechanism in the hydrolysis of aryl N-methylamino-sulphonates

Abstract
PH-independent rate constants for hydrolysis of the title esters obey a Brønsted relationship with β– 1·85; participation of an elimination mechanism involving MeNSO2 intermediate is consistent with the above data (indicating considerable SO bond cleavage in the transition state) with the absence of a glycine buffer effect, and with a 108 fold greater reactivity of the 4-nitrophenyl ester compared with the dimethylamino-ester to reaction with hydroxide ion.
