    铜粉存在下溴二氟乙酸乙酯的反应
    摘要:
    我们已经研究了在铜粉存在下溴二氟乙酸乙酯(1)的反应,作为合成含有CF 2基团的化合物的方法。在上述反应中形成的配合物与乙烯基或芳基碘化物反应,得到交叉偶联产物,与迈克尔受体得到1,4-加成产物,与烯烃得到自由基加成产物。将交叉偶联反应用于4,4-二氟-α-生育酚的合成。

  • The Activation of Carbon−Chlorine Bonds in Per- and Polyfluoroalkyl Chlorides:  DMSO-Induced Hydroperfluoroalkylation of Alkenes and Alkynes with Sodium Dithionite

    omega-dichloroperfluoroalkanes, the similarly stepwise reactions with an alkene is not clean, both bis-adducts and the corresponding omega-hydrides, RCH(2)CH(2)(CF(2))(n)()H as byproducts are also formed. In the absence of alkenes or alkynes, per- and polyfluoroalkyl chlorides can be converted to their sulfinate salts and sulfonyl chlorides.
    在DMSO中,全氟烷基氯,R(F)Cl与烯烃或炔烃的加成反应可以在75-(1.5)Na(2)S(2)O(4)和NaHCO(3)的存在下平稳进行80摄氏度,持续4-10小时,得到相应的加合物(RCH(2)CH(2)R(F)或RCH = CHR(F))。乙基氯氟-(1f),氯二氟-(1g)乙酸酯,甚至非氟化化合物,例如二氯乙基(1h),乙酸氯(1i)和氯仿(1j)也可以进行类似的反应。用> 3当量的烯烃和Na(2)处理ω-碘(或氯)全氟烷基氯化物[X(CF(2))(n)()Cl,n = 2、4,X = I或Cl] S(2)O(4)直接给出对称的双取代烷烃(RCH(2)CH(2))(2)(CF(2))(n)()。对称和非对称双取代的加合物RCH(2)CH(2)(CF(2))(n)()CH(2)CH(2)R' ω-碘全氟烷基氯也可以逐步得到,即通过单加合物RCH(2)CH(2)(CF(2))(n)

  • The Mitsunobu reaction in the synthesis of α,α-difluoro-β-amino acids
    作者:Natalie A. Fokina、Andrei M. Kornilov、Valery P. Kukhar
    DOI:10.1016/s0022-1139(01)00430-4
    日期:2001.9
    A three-stage strategy is proposed to prepare alpha,alpha -difluoro-beta -amino acids starting from aldehydes and with ethyl bromodifluoroacetate as a fluorine source. The Mitsunobu reaction as a key step was studied by P-31 and F-19 NMR for alkyl- and aryl-substituted alpha,alpha -difluoro-beta -hydroxyesters and performed under optimized conditions giving the target compounds.

    We have examined the reaction of ethyl bromodifluoroacetate (1) in the presence of copper powder as a procedure for the synthesis of compounds containing a CF2 group. The complex formed in the above reaction reacted with vinyl or aryl iodides to give cross-coupling products, with Michael acceptors to give 1,4-addition products and with olefins to give radical addition products. The cross-coupling reaction
