| titleOfInvention | Diamino-quinones |
| abstract | The invention comprises quinones of the formula <FORM:0884167/IV (b)/1> wherein R1 is a hydrogen atom or an alkyl radical of 1-4 carbon atoms, e.g. 6 : 7-diamino-5 : 8-quinoline and 5 : 8-quinaldine quinones, and their preparation by reducing the corresponding 2 : 3-diazido-quinones (obtained by the action of sodium azide on the dichloro-compound), suitably by catalytic reduction or by reaction with sodium dithionite and oxidising the resulting diamino-hydroquinone, preferably by blowing in air. The products are isolated as di-acetyl derivatives. |
