| titleOfInvention | Manufacturing process for quinoxalines |
| abstract | The invention relates to a process for the preparation of quinoxalines by condensation of optionally substituted o-phenylenediamine with a diketone according to the following reaction scheme: where: R1, R2 and R3 each independently represent hydrogen or a monovalent, saturated, unsaturated or aromatic hydrocarbon radical with 1 to 20 Are carbon atoms, where one or more carbon atoms are optionally replaced with heteroatoms each independently selected from 0, N, S, F, Cl and Br, and n is an integer from 0 to 4; where optionally two radicals R1 and / or R2 and R3 are bonded to one another and together with the atoms to which they are bonded form a saturated, unsaturated or aromatic ring; and wherein the condensation reaction is carried out in water as a solvent by heating the reactants under pressure to a reaction temperature> 100 ° C. |
