p style="MARGIN: 0cm 0cm 4pt" class="ElsAbstractText">Reactions of methyl 2,5-dichlorobenzoate or methyl 3,6-dichloro-2-methoxybenzoate with sulfur-centered nucleophiles gave mono- and disubstitution products respectively through SRN1 mechanism in liquid ammonia. Products obtained could be potential herbicides less toxic to the environment. Theoretical studies explained the reactivity observed considering geometries, and spin densities of radical anions and potential energy surfaces for the dissociation of the radical anions formed.
