Abstract

Sodium 2 - mercapto - naphtho - 11,21,4,5oxazole - 5 - sulphonate is prepared by refluxing 1 - amino - 2 - hydroxynaphthalene - 4 - sulphonic acid dissolved in aqueous caustic soda with carbon disulphide in methanol. Similarly, the sulphonates of other 2-mercapto-naphthoxazoles are prepared by using the following sulpho-naphthols in the above preparation: 2 - amino - 3 - hydroxynaphthalene - 6 - sulphonic acid, 1 - hydroxy - 2 - aminonaphthalene - 4 - sulphonic acid, 1 - amino - 2 - hydroxynaphthalene - 6 - sulphonic acid or 2 - hydroxy - 3 - amino - naphthalene - 5 : 7-disulphonic acid. Similarly, substituted 2-mercaptobenzoxazoles are prepared by reacting the following aminophenols with carbon disulphide in the above manner; 2-amino-4-chlorophenol-6-sulphonic acid, 2-aminophenol-4-sulphonic acid, 2-amino-6-chlorophenol-4-sulphonic acid (the resulting sulpho-benzoxazole is converted into its barium salt), 3-amino-4-hydroxybenzoic acid, 2-hydroxy-3-amino-benzoic acid, 1 - hydroxy - 2 - amino - benzene - 4 - or 5-sulphonamide, and 1-hydroxy-2-amino-4-methyl-benzene-6-sulphonic acid. Sodium 2 - mercapto - naphtho - 11,81; 4,6-oxazine-8-sulphonate is prepared by the above method from 1-amino-8-hydroxynaphthalene-6-sulphonic acid and carbon disulphide. By using 1 - hydroxy - 8 - amino - 3,6 - disulphonic acid the corresponding naphthoxazine-5 : 8-disulphonate is obtained. Sodium 2 - mercaptobenzthiazole - 5 - sulphonate is obtained by first adding the sodium salt of 2 - nitrochlorobenzene - 4 - sulphonic acid to an aqueous solution of sodium sulphite, and then adding carbon disulphide and refluxing. Instead of the nitrochlorobenzene compound referred to above the following compounds may be used to give substituted 2-mercaptobenzthiazoles: 1 - chloro - 2 - nitrobenzene - 4 - methylsulphonamide, 1 - chloro-2 - nitro - benzene - 4 - (p - chlorophenylsulphonamide or 4 - chloro - 3 - nitrobenzoic acid. By a similar reaction using potassium selenide instead of sodium sulphide, 2-mercapto-5-sulpho-benzselenazole is obtained. This reaction also is performed using 4-chloro-3-nitrobenzoic acid. Sulphonic acid derivatives of 2 - mercapto - 6 : 7 - benzo - benzthiazole and 2-mercapto-benzthiazine are prepared by sulphonating them with oleum at 20 DEG C.
