    引入4-氟环己基2,5-二壬烯作为豪瑟环化反应的新受体。在相应的甲氧基类似物不能进行环合的情况下,前者可以与苯磺酰邻苯二甲酸酯一起顺畅地进行,从而以高收率提供蒽醌。涉及立体效应来解释甲氧基类似物的惰性。

  • The role of F–N reagent and reaction conditions on fluoro functionalisation of substituted phenols
    作者:Igor Pravst、Maja Papež Iskra、Marjan Jereb、Marko Zupan、Stojan Stavber
    DOI:10.1016/j.tet.2006.02.051
    日期:2006.5
    The effect of steric interactions on the regioselectivity of fluorination of para alkyl substituted phenols was investigated and the strong effect of size of the alkyl substituent, the structure of the F–N reagent and the solvent on the site of fluorination was established. The course of reaction obeyed a second order rate equation, while the fluorination process required higher ΔH≠ activation than
    研究了空间相互作用对对烷基取代酚的氟化区域选择性的影响,并确定了烷基取代基的大小,F-N试剂的结构和溶剂对氟化位点的强烈影响。反应过程服从二级速率方程,而氟化过程需要比氧化或氧化脱甲基更高的ΔH ≠活化。溶剂极性变化对官能化速率的影响很小,同时确定了与ρ + = -2.3的极好的Hammett相关性。

    The invention provides a process for the preparation of 4,4-disubstituted cyclohexadienones of which at least one of the substituents is fluorine, which comprises reacting a compound of formula ##STR1## wheren X represents a hydrogen or halogen atom or an alkyl group, each R independently represents a halogen atom or an alkyl, alkoxy, or cyano or optionally substituted amino group, Z represents a hydrogen atom or an alkyl, acyl or aryloxycarbonyl group, and n is 0 to 4, with hydrogen fluoride and a Pb(IV) compound, in the presence of a compound which acts as a base towards HF.
    该发明提供了一种制备4,4-二取代环己二酮的方法,其中至少一个取代基是氟,包括将式化合物与氢氟酸和Pb(IV)化合物在化合物存在下反应,其中X代表氢原子或卤素原子或烷基,每个R独立代表卤素原子或烷基、烷氧基、氰基或可选的取代氨基团,Z代表氢原子或烷基、酰基或芳氧羰基团,n为0至4,并且在存在一化合物作为对氢氟酸的碱的情况下进行。
  • Substituent modulation of mild fluorination of aromatic molecules with caesium fluoroxysulphate
    作者:Stojan Stavber、Zdenka Planinšek、Iztok Košir、Marko Zupan

    日期:1992.12
    benzene derivative with CsSO4F has been modulated by substituents on the benzene ring. α-Hydroxyalkylbenzenes, with a deactivated ring, were oxidized to phenones, while fluorodealkylation was achieved in high yield when electron-donating groups were present in a para position. Electron-withdrawing substituents favoured chain fluorofunctionalization in alkylbenzenes, while ring fluorination was found
    用CsSO 4 F取代单取代和二取代的苯衍生物的功能已被苯环上的取代基所调节。具有失活环的α-羟基烷基苯被氧化为苯酮,而当给电子基团存在于对位时,可以高收率实现氟脱烷基化。吸电子取代基有利于烷基苯中的链氟官能化,而环氟化仅存在于酰基氨基衍生的烷基苯中。在ρ-烷氧基取代的烷基苯衍生物的情况下,形成氟加成产物。
  • Efficient Synthesis of 4-Fluorocyclohexa-2,5-dienone Derivatives Using N-Fluoro-1,4-diazoniabicyclo[2.2.2]octane Salt Analogues
    作者:Stojan Stavber、Marjan Jereb、Marko Zupan
    DOI:10.1055/s-1999-2840
    日期:1999.9
    4-Fluorocyclohexa-2,5-dienone derivatives were obtained in high yield by reaction of para substituted phenols with 1-fluoro-4-chloromethyl-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoro-borate) (1a, SelectfluorTM F-TEDA-BF4) or its 4-hydroxy analogue (1b, AccufluorTM NFTh) in acetonitrile. Estrogen steroids were readily converted to 10β-fluoro-1,4-estradiene-3-one derivatives in high yields.

    4-fluorocyclohexa-2,5-dienones in a good yield. (R,S)-1,1′-Bi-5,6,7,8-tetrahydro-2-naphthol (and its monoacetate) yields atropoisomeric fluorocyclohexadienones. The 4-substituted carbamate open-chain phenols were readily converted to fluorohydroindolenone and fluorohydroquinolenone derivatives by intramolecular conjugate addition.
