Process for the preparation of substituted 3- and 4-(pentafluorosulfanyI)benzenes of general formula 3 and 4 by nucleophilic aromatic substitution, where nitrobenzene having pentafiuorosulfanyl group connected in position 3 or 4 is allowed to react in concentration range 0.01 to 8.0 mol.l-1 with compound RY-M+, where R is selected from a group comprising saturated, unsaturated, acyclic, cyclic or aromatic, substituted or unsubstituted carbon chain, Y is the element of VI. B group and M+ is the metal ion, in an organic solvent. The invention includes also further chemical modifications of primary products.
通过亲核芳香取代法制备通式3和4的取代3-和4-(五氟硫基)苯的过程,其中允许在浓度范围为0.01至8.0 mol.l-1的条件下,将具有连接在3位或4位的五氟硫基团的硝基苯与化合物RY-M+发生反应,其中R选自包括饱和、不饱和、无环、环状或芳香的取代或未取代碳链的一组,Y是VI.B族元素,M+是金属离子,在有机溶剂中。该发明还包括对初级产物的进一步化学修饰。
