| titleOfInvention | PROCEDURE FOR THE PREPARATION OF DI-N-OXIDES OF QUINOXALINE AND THE LIKE. |
| abstract | Quinoxaline-di-N-oxides are prepared by reacting benzofuroxans and #-diketo compounds in the presence of liquid tertiary amines. The process may be used to prepare the novel quinoxaline-di-N-oxides of the general formula wherein R 1 represents an alkyl-(C 1-6 ) or monocarbocyclic aryl group and R 2 represents an alkyl-(C 1-6 ), alkoxy-(C 1-6 ) or monocarbocyclic aryl group. 2-Phenyl-quinoxaline-di-N-oxides may also be prepared by reacting dibenzoylmethanes and benzofuroxans in alcoholic alkali metal hydroxide. Quinoxalines are prepared by reducing the above quinoxaline-di-N-oxides with sodium dithionite. 2 - Phenylquinoxaline - di - N - oxide is prepared by treating 2-phenyl-3-benzoyl-quinoxaline - di - N - oxide with methanolic potassium hydroxide. |
