| titleOfInvention | Method of producing anthra(b)furandiones |
| abstract | The invention relates to heterocyclic compounds, in particular to the preparation of anthraf furandion (AF), of the general formula O RI "RI Kz where the two adjacent substituents R -R form the group -CH-CH C-CgH, 0a the third radical is hydrogen, which can be used as dyes. The goal - the creation of new (AF) new way. The preparation of AF is carried out from halogen-hydroxyanthraquinones of the general formula O Rii where halogen, H, OH; Rj is OH, halogen; Rj is H or halogen, and R, R5, RJ have different meanings, and at the same time one of them is an OH group, the other is a hydrogen atom and the third is a halogen atom, and the corresponding copper acetylide of the general formula: () C, where phenyl, OCH., In an aprotic organic solvent medium, in an inert atmosphere, at room temperature until the reaction mixture boils. The method provides the yield of the target compounds to 58-79%. (Ls |
