Method for preparing 5 and 6-nitro derived 1,2,3,4- tetrahydroanthraquinone from 1,2,3,4,4a,9a-hexahydro- 9,10 anthracenedione |
| abstract |
ABSTRACT DESCRIPTION Process for the preparation of mononitrated derivatives in position 5 or 6 of tetrahydro-1,2,3,4 anthraquinone charac-terized in that we submit the hexahydro-1,2,3,4,4a, 9a anthra-cene-dione-9.10 at a nitration, using nitric acid or a mixture of nitric acid and sulfuric acid. We obtain thus selectively and with excellent yields the derivatives monosubstituted in positions 5 and 6, |
