Abstract Rate constants for a wide range of binary aqueous mixtures and product selectivities (S) in ethanol–water (EW) and methanol–water (MW) mixtures, are reported at 25 C for solvolyses of benzenesulfonyl chloride and the 4-chloro-derivative. S is defined as follows using molar concentrations: S=([ester product]/[acid product])×([water solvent]/[alcohol solvent]). Additional selectivity data are reported for solvolyses of 4-Z- ...
