Abstract

The solvolysis rates of 2, 2-dimethyl-3-(trimethylsilyl) propyl and 3-(aryldimethylsilyl)-2, 2- dimethylpropyl p-toluenesulfonates were measured in a wide variety of solvents at 45° C. The solvent effects were analyzed by using the Winstein–Grunwald equation. The solvent effects observed did not give simple linear correlations with the 2-adamantyl Y OTs parameter, but showed dispersion behavior in a series of binary solvents. The m values of ...
