Заглавие : Crystalline hydrogen-bonded adducts of dimethyl sulphoxide and 7-hydroxypolyfluoroquinolones (chromones Место публикации : Journal of Fluorine Chemistry. - 1995. - V. 74. - С. 15-19 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A stable crystalline hydrogen-bonded adduct of dimethyl sulphoxide (DMSO) and 7-hydroxy-5,6,8-trifluoro-2-carboxychromone has been prepared by the reaction of 2-carboxy-5,6,7,8-tetrafluorochromone with KOH/glycerol in DMSO. It has been found that pentafluorophenol and also 1-cyclohexyl-7-hydroxy-5,6,8-trifluoro-4(1H)-4-oxoquinoline-2-carboxylic acid form the corresponding crystalline hydrogen-bonded adducts with DMSO. The structure of the latter has been established from an X-ray crystallographic study Доп.точки доступа: Saloutin, V. I.; Bazyl, I. T.; Skryabina, Z. E.; Alexandrov, G. G.; Chupakhin, O. N.
