  • First application of ionic liquids in electrophilic fluorination of arenes; Selectfluor™ (F-TEDA-BF4) for “green” fluorination

  • Fluorination of Fluorene, Dibenzofuran and Their Open Analogues with Caesium Fluoroxysulfate and Related Fluorinating Reagents
    作者:Jernej Iskra、Stojan Stavber、Marko Zupan
    DOI:10.1135/cccc20081671
    日期:——

    Fluorination of fluorene (1) with caesium fluoroxysulfate (CFS), 2,6-dichloro-1-fluoropyridinium tetrafluoroborate (FP-B800) and 1-fluoro-4-hydroxy-1,4-diazoniabicyclo[2.2.2]- octane bis(tetrafluoroborate) (Accufluor NFTh) occurred only on the aromatic ring in the position ortho and para to the biphenyl central bond with the ratio 2-fluoro- (2a) vs 4-fluorofluorene (2b) 1.7-2.4:1. Regioselectivity of fluorination of both open-chain analogues - diphenylmethane (3a) and biphenyl (3b) was different and more ortho-fluorinated product was formed. Furthermore, the reaction of diphenylmethane (3a) with CFS occurred also on central carbon forming benzophenone (6) and fluorodiphenylmethane (7), while fluorination with FP-B800 and Accufluor NFTh occurred only at the aromatic ring. Similar effect of the structure of fluorinating reagent on the regioselectivity was also observed with dibenzofuran (8) and its open-chain analogues diphenyl ether (10) and biphenyl (3b), where the regioselectivity of fluorination with CFS (1- (9a):2- (9b):3- (9c) = 27:46:27) was similar to fluorination with Selectfluor. Product distribution of fluorination of fluorene (1) and dibenzofuran (8) with CFS is similar to nitration and is in accordance with the calculated HOMO electron density, which indicates the presence of the electron transfer pathway.

    对于氟化反应,使用氟氧硫酸铯(CFS)、2,6-二氯-1-氟吡啶四氟硼酸盐(FP-B800)和1-氟-4-羟基-1,4-二氮杂双环[2.2.2]-辛烷双(四氟硼酸盐)(Accufluor NFTh)仅在芴分子的芳香环上发生,位置为联苯中心键的邻位和对位,生成2-氟芴(2a)和4-氟芴(2b)的比例为1.7-2.4:1。对于开链类似物-二苯甲烷(3a)和联苯(3b)的氟化反应选择性不同,更多的邻位氟化产物被形成。此外,二苯甲烷(3a)与CFS的反应也发生在中心碳上,生成苯并酮(6)和氟代二苯甲烷(7),而与FP-B800和Accufluor NFTh的氟化反应仅发生在芳香环上。氟化试剂结构对反应选择性的影响也在二苯并呋喃(8)及其开链类似物二苯醚(10)和联苯(3b)中观察到,使用CFS的氟化选择性(1-(9a):2-(9b):3-(9c)= 27:46:27)类似于Selectfluor的氟化选择性。芴(1)和二苯并呋喃(8)与CFS的氟化产物分布类似于硝化反应,并与计算的HOMO电子密度一致,表明存在电子转移途径。
