Abstract
2-(p-aminophenyl) -5- amino thiodiazole-1:3:4 compounds which are substituted in the phenyl amine group by one or two straight or branched chain alkyl radicals the longest carbon chain of which contains not more than 6 carbon atoms are prepared by the treatment of the corresponding p-alkylamino-benzoic acid and 2 mols of thiosemicarbazide with polyphosphoric acid at 120 DEG C. The polyphosphoric acid acts as a dehydrating agent and effects ring closure. After about two hours the reaction mixture is poured on to ice and made alkaline (pH 8-9), the precipitated thiodiazole compound being filtered off, recrystallized e.g. from ethanol, and dried. Brief details are given in the case of compounds having NN-dimethyl, -diethyl, -ethyl-n-propyl, -di-n-propyl, N-ethyl, -npropyl, and -isoamyl substituents. The compounds are used as photo conductors in electrophotographic materials.
