Thiophenols of the formula <IMAGE> in which R1, R2, R3 and R4 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, R5 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 <IMAGE> 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 <IMAGE> 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.
