Reactivity of methoxide ion in concentrated methanolic solutions of Et4NOCH3 and Et4NCl

Bimolecular rate constants k were determined for reactions of 4-nitrophenyl 4-toluenesulfonate, diethyl 4-nitrophenyl phosphate, and ethyl 4-nitrophenyl ethylphosphonate with tetraethylammonium methoxide Et4NOCH3 in methanol at 25°C over a wide range of Et4NOCH3 concentrations, where the reagent acts simultaneously as electrolyte, and at [Et4NOCH3] ≤ 0.1 M (reagent) with variation of Et4NCl (electrolyte) concentration. The relation logk = logk0 + b[Et4NX] is fulfilled up to [Et4NX] = 3.5 M, indicating that the electrolyte affects the reaction rate through restructurization of methanol as reaction medium.
