Patent GB-298493-A (GB)
Abstract: 298,493. I. G. Farbenindustrie Akt.- Ges. Oct. 8, 1927, [Convention date]. Alkoxy - 3 - oxythionaphthenes; alkoxyarylthioglycollic acid halides. - Alkoxy-3-oxythionaphthenes are prepared by treating an alkoxyarylthioglycollic acid halide of the benzene or naphthalene series with an aluminium halide, preferably in the presence of a solvent. The alkoxyarylthioglycollic acids themselves are advantageously used as starting materials, the solutions of the acid halides prepared therefrom being directly treated with aluminium halide. The alkoxyarylthioglycollic acids may contain other groups in the nucleus, e.g. alkyl groups and halogens. In examples, 1-methyl-6-chlor-4-methoxybenzene- 3-thioglycollic acid and 6-ethoxynaphthalene-2- thioglycollic acid in chlorbenzene are converted into the acid chlorides by means of thionyl chloride and phosphorus trichloride respectively. Aluminium chloride is slowly added with gentle heating and the solvent steam distilled, whereby the corresponding alkoxy-3-oxythionaphthenes are obtained. 4-Ethoxynaphthalene - 1 - thioglycollic acid is also mentioned as starting material. 4- and 6-Ethoxynaphthalene - 2 - thioglycollic acids are prepared by reducing the ethoxynaphthalene-2-sulpho chlorides to the corresponding mercaptans and condensing with chloracetic acid. Specification 14191/06 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of 7- methoxynaphthalene-1-and 2-thioglycollic acids and 4-ethoxynaphthalene-2-thioglycollic acid. This subject-matter does not. appear in the Specification as accepted.
