Abstract

The effects of lithium perchlorate on acetolysis rate of 0-and p-anisylethyl p- toluenesulfonates have been contrasted with those observed with the phenylethyl, neophyl and p-methoxyneophyl esters. With the 0-and p-anisylethyl derivatives, lithium perchlorate exerts both" special" and" normal" salt effects. The former designation refers to a very steep rise in titrimetric rate constant, kt, from the base value, kto, due to low concentrations of ...
