| titleOfInvention | Process for the preparation of 2,2'-imino-bis benzothiazole compounds |
| abstract | An improved process for the preparation of 2,2'-imino-bis-benzothiazole compounds, in which a 2-amino-benzothiazole compound at a temperature above 130 ° C. in the presence of an acidic compound, optionally in a high-boiling solvent, or in a high-boiling solvent and without an acidic compound, in particular at a temperature of 200 ° C. The high-boiling solvent can preferably be an acid solvent. The acidic compound can be used in catalytic amounts up to stoichiometric amounts; acidic compounds are, for example, hydrochloric acid, sulfuric acid, phosphoric acid or a phenol. The 2,2'-imino-bis-benzothiazoles produced by this process are obtained in pure form and in high yield; they can be used for further processing directly in known subsequent reactions without further purification. The new process avoids starting products which are difficult to access and the formation of the toxic methyl mercaptan according to known processes. |
