  2,4-Bridged 1,5-bis(fluoroalkyl)-1,3,5-triketones: synthesis and properties

  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.
