The mechanism of conversion of o-nitrothiophenols into o-aminobenzenesulphonicacids in aqueous dioxane has been investigated with particular reference to evidence for the rate-determining formation of a cyclic intermediate. This intermediate is susceptible to interception by both external and internal nucleophilic functions, and the sulphonic acid is shown by isotope labelling experiments to take
