Abstract

The solvolyses of cyclopropylmethyl derivatives are accelerated and seem to proceed through the formation of non-cla1ssical carbornium i'Onsn. These reacti•ons are a•ls:o very often accompa1111ied by extensive rearrangements6 • Thus, the acetolysis of cyc1opropylmethyl benzenesulfonate proceeds simultaneously w;ith a competitive internal rearrangement to products which are 250 times less reactive than the starting materiaF. In the course of our investigation o[ the mecha111ism of these two closely related reactions, we w&nted to gain some information aibout the. corresponiling free energies and entropies of activation.
