Abstract

σHet Values for thia- and oxa-substituents in five-membered heterocycles are derived from the rate constants for the reactions of sulphonyl chlorides with aniline in methanol. These values, which are negative and similar to σ+, are in agreement with the S AN mechanism previously proposed.
