Abstrakt: Cyanoethylation of 4-aryl-1, 2, 4-triazolinethiones-3 takes place at the nitrogen atom of the thioamide group, to give N-cyanoethyl derivatives. ß-Chloropropionitrile reacts at the nitrogen atom of the thioamide groups, but ß-chloropropionic acid reacts at its sulfur atom, giving a sulfide. The results of cyanoethylation enable conclusions to be drawn regarding the shift of the reaction center from sulfur to nitrogen on passing from a tetrazole to a triazole derivative.
