Заглавие : Synthesis of 1,1,1,7,7,7-hexafluoroheptane-2,4,6-trione, the simplest fluorinated 1,3,5-triketone Место публикации : Journal of Fluorine Chemistry. - 2006. - Vol. 127, № 7. - С. 983-986 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A simple, convenient and effective method to synthesize 1,1,1,7,7,7-hexafluoroheptane-2,4,6-trione, the simplest fluorinated 1,3,5-triketone, on a preparative scale was developed. The title compound was obtained by a Claisen-type double condensation of acetone with trifluoroacetic acid ethyl ester and isolated as a solid monohydrate from the reaction mixture. Subsequent dehydration proceeds smoothly to produce the desired compound as an individual substance. Its peculiar tautomeric (keto–enol, ring–chain) features in various solvents are discussed Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Sevenard, D.
