Abstract

Abstract For solvolyses of various benzyl substrates in ethanol–water (EW) and methanol– water (MW) mixtures, product selectivities (S) are reported for chlorides at 75 C defined as follows using molar concentrations: S=([ether product]/[alcohol product])×([water]/[alcohol solvent]). The results support earlier evidence that solvolyses of 4-nitrobenzyl substrates are SN 2 processes, which are not susceptible to mechanistic changes over the whole range ...
