Abstract
The purpose of this investigation was to determine the rates of solvolysis of 2,4-dicarbomethoxybenzyl bromide and 2. 4-dicyanobenzyl bromide at 45 °C. and the rates of solvolysis of the latter compound, and para-carbomethoxybenzyl bromide at 55 °C. in 50% aqueous acetone. Another aim of this investigation was to obtain the energies of activation of solvolysis of 2. 4-dicyanobenzyl and para-carbomethoxybenzyl bromide. The presence of the ortho substituents in the 2,4-compounds lends itself to the following discussion of the ortho effects.
