Abstract

The synthesis and spectroscopic characterisation of some representative N-alkylsubstituted quaternary ammonium salts derived from benzothiazole, benzoxazole, benzoselenazole, indole and quinoline are described. These heterocyclic salts, bearing an activated methyl group in the 2-position in relation to the nitrogen atom and N-methyl, -pentyl, -hexyl and -decyl chains, are typical precursors of cyanine dyes.
Keywords: Heterocyclic quaternary ammonium salts; cyanines precursors; spectroscopic characterisation Heterocyclic quaternary ammonium salts; cyanines precursors; spectroscopic characterisation
