摘要：

A kinetic and thermodynamic analysis of the reactions of hydroxylamine with aryltoluenesulfonates in H2O-DMSO mixtures (0-90 vol.% DMSO) indicated that the neutral and anionic forms of hydroxylamine are strong α-nucleophiles, and the magnitude of the α-effect shows an asymmetric bell shape depending on the DMSO content. This phenomenon is interpreted. © 1999 Kluwer Academic/Plenum Publishers.
