Abstract

Quaternary salts of a 2-(substituted mercapto) pyridine or quinoline are made by heating one molecular proportion of a mercaptan with one molecular proportion of a quaternary salt of an iodo derivative of a heterocyclic nitrogen base of the formula <FORM:0454687/IV/1> wherein R is an alkyl or substituted alkyl group, R<11> stands for a vinylene, phenylene, or a substituted vinylene or phenylene group, and X for an acid radicle. Reaction may take place in a diluent and an acid-binding agent such as a tertiary organic base is preferably present. In examples: 2-iodoquinoline ethiodide is condensed with phenylmercaptan, p - tolylmercaptan, b - naphthylmercaptan, p-chlorphenylmercaptan, 2.5 - dichlorphenylmercaptan, n-propylmercaptan, n-butylmercaptan; 2-iodo-6-methylquinoline ethiodide is condensed with b -naphthyl mercaptan; 2-iodopyridine methiodide is condensed with b - naphthylmercaptan, 2.5 - dichlorphenylmercaptan and 2-p-chlorphenylmercaptan; in all cases condensation is effected in alcohol in presence of triethylamine. Reference is also made to the production of 2-mercaptans of pyridinium or quinolinium salts wherein attached to the sulphur atom is a benzyl, benzthiazole or pyrazolone radicle. The products are of use in the production of cyanine dyes.
