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

Abstract
σHet Values for thia- and oxa-substituents in five-membered heterocycles are derived from the rate constants for the reactions of suiphonyl chlorides with aniline in methanol. These values, which are negative and similar to σ+, are in agreement with the SAN mechanism previously proposed.File in questo prodotto:
