Solvent Effects on the Solvolyses of N-Benzoyl Chlorides

Abstract

Rates of solvolyses of N-benzoyl-arenesulfonimidoyl chlorides have been studied in different compositions of aqueous organic solvents and analysed in terms of the mol fraction of organic solvent, the dielectric constant, the Kirkwood function, the polarisibility, some EN<inf>T</inf> values, a multiparameter equation and the Grunwald-Winstein equation. All these criteria were consistent with a concerted bimolecular S<inf>N</inf>2 mechanism of solvolysis.
