| titleOfInvention | Fluorinated aromatic amino acids and amide derivatives thereof |
| abstract | The invention comprises p-amino-tetrafluoro-benzoic acid NH2.C6F4.COOH, its amide and its N-diethyl amide; diamino-trifluorobenzoic acid and the corresponding amide and N-diethyl amide. The new compounds of the formula NH2.C6F4COX, where X is -OH, -NH2 or -N(C2H5)2, are made by reacting a compound of the formula C6F5COX with sodamide in liquid ammonia. The amides may also be made by reacting C6H5COX with alcoholic ammonia at elevated temperature and pressure, e.g. in an autoclave. Diaminosubstituted compounds may be obtained by this method if heating continues for long enough. The p-amino-tetrafluorobenzoic acid or di-amino-trifluorobenzoic acid may be obtained from the corresponding unsubstituted amide by alkaline hydrolysis, e.g. with 20% NaOH solution, followed by acidification. Detailed examples are given. |
