Abstract
1,274,071. Heterocyclic sulphur compounds. AGFA-GEVAERT A.G. 5 Aug., 1969 [6 Aug., 1968], No. 39066/69. Heading C2C. [Also in Division G2] Compounds are described which are the condensation products of one molecular proportion of phosgene with two molecular proportions of a heterocyclic mercaptan of the triazole, oxazole, thiazole, imidazole, thiadiazole or thiadiazoline series. In examples, phosgene in CCl 4 solution is added to alkaline solutions of 1-phenyl-3- mercapto-1 : 2 : 4-triazole, 2-mercapto-5-anilino-1 : 3 : 4-thiadiazole, 2-mercapto-benzothiazole, 2-mercapto-benzoxazole, 2-mercapto- 4 : 5-di(p-chlorophenyl)-3-phenylimidazole, 2- mercapto-5-thioxo-4-phenyl-1: 3 : 4-thiadiazoline, 2-mercapto-5-butyl-mercapto-1 - 3 - 4-thiadiazole and 2-amino-5-mercapto-1: 3 4-thiadiazole. The condensation products may be heterocyclyl S : S<SP>1</SP>-diesters of dithiocarbonic acid formed by the phosgene reacting at the mercapto groups, or bis-heterocyclic ketones formed by the phosgene reacting with hydrogen on the nitrogen atom of the tautomeric thione form of the heterocyclic mercaptan.
