摘要： Triazoles of the formula ##STR1## in which R.sub.1 is hydrogen or a substituent of the type indicated in the description,R.sub.2 is a substituent, orR.sub.1 and R.sub.2, together with the triazole ring carbon atoms to which they are bonded, form a carbocyclic or heterocyclic ring, andR.sub.3 is the radical of an aromatic-carbocyclic or aromatic-heterocyclic system,are obtained in an elegant manner when compounds of the formula II are treated with a basic compound, preferably a tertiary amine. The triazoles are, inter alia, valuable starting materials for the preparation of optical brighteners.
