Results of an investigation are presented in which S//N reactions of dichlobenil and its transformation products were investigated using as nucleophilic agents for chlorine exchange: sodium methanolate and ethanolate, as well as aniline and its derivatives. It has been shown that the ability to enter the reaction of mono- or disubstitution is dependent on the kind of derivative of 2,6-dichloro-3-nitrobenzoic acid, as well as on conditions of reactions. In the manner described above, dichlobenil has been transformed into valuable herbicide, dicamba, i. e. 3,6-dichloro-2-methoxybenzoic acid. A mixture of isomeric acids has been obtained, their herbicide activity having the same range.
