Abstract: In the prodn. of quaternised azo dyestuffs L-het-N=N-K Ane (I) by reacting the neutral dye base Het-N=N-K (II) with an alkylating agent L-X (III), the novelty is that gamma-butyrolactone (IV) is used as the inert diluent. In (I)-(III) Ane = the equiv. of an anion; L = 1-4C alkyl; Het = a 5-membered aromatic heterocycle, which may be benzo-annellated and contains at least one N atom and 1 or 2 other hetero-atoms, selected from N, O and S, which is linked to L at a N atom; K = the radical of a coupling component of the aniline series; X = a labile gp.. Pref. (III) is di(m)ethyl sulphate. USE/ADVANTAGE - (IV) is readily biodegradable and serves well as medium for (I), allowing the reaction soln. to be used directly, without changing the diluent. (I) are obtd. in high yield and high purity and are useful for dyeing polyamide or polyacrylonitrile texti

Abstract: Triazolopyridines of the formula where R1 is C1-C20-alkyl which may be substituted, phenyl which may be substituted, or hydroxyl, R2 is hydrogen, formyl, nitroso, cyano or substituted methyl, R3 is hydrogen, cyano, carbamoyl, carboxyl or C1-C4-alkoxycarbonyl and R4 is hydroxyl, halogen, amino which may be substituted or the radical of a compound with an acidic CH, are prepared as described. The compounds are useful as intermediates in the preparation of dyes.
