Correlation of the rates of reaction of arenesulfonate ions with the trimethyloxonium ion in acetonitrile1

Add time:07/29/2019    Source:sciencedirect.com

The kinetics of the reactions between trimethyloxonium hexafluorophosphate and a series of tetra-n-butylammonium arenesulfonates have been studied in acetonitrile at −23.4°. With the oxonium salt concentration at about 0.01 M, two series of runs were carried out; Hammett plots of the second-order rate coefficients led to ϱ values of −1.18±0.04 for 0.04 M arenesulfonate salt and −1.07±0.02 for 0.16 M arenesulfonate salt. Solvolysis kinetics for the trimethyloxonium ion in acetonitrile are also reported.
