Thiophenols of the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently of each other each stand for hydrogen, halogen, nitro, alkyl, alkoxy, alkylthio, alkoxyalkyl, alkylthioalkyl, haloalkyl, haloalkoxy or alkylcarboxyl, optionally substituted aryl or optionally substituted hetaryl, R.sup.5 stands for alkyl, alkoxyalkyl, alkylthioalkyl, haloalkyl, alkenyl, haloalkenyl, optionally substituted aryl or optionally substituted hetaryl, and X stands for carbonyl, sulphinyl or sulphonyl can be obtained by reacting halobenzenes of the formula ##STR2## in which Hal stands for halogen, first with sodium hydrogen sulphide or sodium sulphide in the presence of a diluent to form compounds of the formula ##STR3## and then adding an acid to form the thiophenol, some of the thiophenols are novel and all can be used to form aryethioaminopyridides which are employed as herbicides.
公式为##STR1##的硫代苯酚,其中R.sup.1,R.sup.2,R.sup.3和R.sup.4独立地代表氢,卤素,硝基,烷基,烷氧基,烷硫基,烷氧基烷基,烷硫基烷基,卤代烷基,卤代烷氧基或烷基羧基,可选择取代芳基或可选择取代杂环基,R.sup.5代表烷基,烷氧基烷基,烷硫基烷基,卤代烷基,烯基,卤代烯基,可选择取代的芳基或可选择取代的杂环基,X代表羰基,亚磺酰基或磺酰基,可以通过将公式为##STR2##的卤代苯与二硫化氢钠或硫化钠在稀释剂的存在下反应形成公式为##STR3##的化合物,然后加入酸形成硫代苯酚,其中一些硫代苯酚是新型的,所有硫代苯酚都可用于形成芳基硫代氨基吡啶,后者可用作除草剂。
