Abstract

306,575. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Nov, 18, 1927. o-Cyanosulphocyano, o-cyanomercapto- and ocyanothioglycollic-aryl derivatives.-An o-aminoarylsulphocyano compound in which the p-posiÀ tion to the amino group is occupied or forms part of a further ring, and which may be prepared according to Specifications 257,619 and 303,813, is diazotized and subjected to Sandmeyer's reaction in order to replace the amino group by a cyano group. The sulpho cyano group is then saponified by means of alkali and the resulting mercapto group finally coupled with chloracetic acid in order to give an o-cyanoarylthioglycollic acid. In examples, 1-methyl-2-amino-3-sulphocyano-5-chlorbenzene, 1-amino-2-sulphocyano-4- ethoxybenzene and 2-amino-1-sulphocyanonaphthalene are used as starting materials, 1-methyl- 2-cyano-5-chlorbenzene-3-thioglycollic acid, 1- ,C,yano-4-ethoxyber.zeiie-2-thiogiyeollic, acid and 2- cyanonaphthalene-1-thioglycollic acid being respectively produced. Specification 295,295 also is referred to.
