  摘要：

  开发了一种有效且可靠的方法来合成 4 位具有各种取代基的 2,6-双（三氟乙酰基）苯酚。这些有价值的氟化结构单元是从相应的环己酮中以简单方便的方法获得的，证明优于传统方法。将该方法应用于 cyclohex-ane-1,4-dione 开辟了获得 2,5-bis(polyfluoroacyl)-1,4-hydroquinones 的途径。在多核 NMR 光谱的基础上讨论了所得酚及其 1,3-二羰基或 1,3,5-三羰基前体的结构特性。

  摘要：

  Symmetrical and unsymmetrical bis-fluoroacylcyclopentanones and cyclohexanones were synthesized. NMR data reveal that the keto-enol tautomeric equilibrium is changed markedly by the presence of a trimethylene bridge compared to an ethylene moiety. A considerable influence of the fluoroalkyl chain length was found for 2,6-(bisfluoroacyl)cyclohexanones. (C) 2003 Elsevier B.V. All rights reserved.
