Chemical Reaction Mechanisms

It is pretended to establish the relative order of reactivity of bis-(2,4-dinitrophenyl) ether and bis-(2,4-dinitrophenyl) thioether, towards acetate, thioacetate, benzoate and thiobenzoate anions in methanol – acetone (1:1), by following the development of said reactions by HPLC. Acetate, thioacetate, benzoate and thiobenzoate anions act as nucleophilic reagents towards both substrates, attacking them by means of a bimolecular nucleophilic aromatic substitution
