Abstract

549,204. Thioesters. KENDALL, J. D. April 7, 1941, No. 4604. Samples furnished. [Class 2 (iii)] Dyestuff intermediates are prepared by condensing a quaternary ammonium salt of a heterocyclic nitrogen compound containing a reactive methyl or mono alkyl substituted methyl group in α or y position with an excess of a compound having the formula S = C(SR) 2 wherein R is an alkyl or aralkyl group in the presence of a base and a solvent. In examples, dimethyltrithiocarbonate is condensed in the presence of triethylamine and alcohol with 1 - methylbenzthiazolmethyltoluenesulphonate, quinaldinemethiodide, 4:5-dimethoxy-1-methyl benzthiazolethyl - p - toluenesulphonate and 1:4 - dimethylbenzthiazolethyl - p toluenesulphonate. By treating the products with alkyl or aralkyl esters, quaternary ammonium salts which are also intermediates are obtained (cf. Specification 549,202). Dyestuffs in small quantities are obtained together with the products (cf. Specification 549,203). Quaternary ammonium salts containing reactive methyl groups for use as starting materials may be derived from oxazoles, selenazoles and thiazoles of the benzene, naphthalene, acenaphthene and anthracene series, pyridine and its polycyclic homologues indolenines, pyrimidines, quinazolines, thio- #:#<SP>1</SP>-diazol, oxazolines, thiazolines, selenazolines and their amino, hydroxy, alkoxy, methylenedioxy and halogen substitution derivatives. Samples have been furnished under Sect. 2 (5) of products obtained by condensing (1) dimethyltrithiocarbonate with 1-ethylbenzthiazolmethyl - p - toluenesulphonate and (2) dibenzyltrithiocarbonate with 1-methylbenzthiazolmethyl-p-toluenesulphonate. Dibenzyltrithiocarbonate is obtained by treating with benzylchloride the aqueous potassium trithiocarbonate prepared by dissolving in water the product obtained by reacting carbondisulphide with alcoholic potash saturated with hydrogen sulphide.
