    Synthesis and Reactivities of 1,5- and 1,7-Azulenequinone Derivatives. A Highly Convenient, One-Pot Synthesis of 3-Bromo-1,5- and −1,7-Azulenequinones by Bromination of Azulene,
    摘要:
    AbstractA very convenient, one‐pot synthesis (over 80% yield) of 3‐bromo‐1,5‐ and −1,7‐azulenequinones has been developed by bromination of azulene in aqueous tetrahydrofuran. Reduction of 3‐bromo‐1,5‐ and −1,7‐azulenequinones with tin or zinc powder in acetic acid gave the parent 1,5‐ and 1,7‐azulenequinones, and further reduction products.

  • The First Synthesis of 1-Fluoro- and 1,3-Difluoroazulenes
    作者:Tetsuya Ueno、Haruhiko Toda、Masafumi Yasunami、Masaaki Yoshifuji
    DOI:10.1246/cl.1995.169
    日期:1995.3
    1-Fluoro- and 1,3-difluoroazulenes were synthesized by the reaction of azulene with N-fluoropyridinium salts in acetonitrile. Methyl azulene-1-carboxylates were also fluorinated to give the corresponding 3-fluoro derivatives. On the basis of the UV-visible absorption spectra, the fluorine atom acts as an electron-donating group to the azulene π-system due to the +Iπ effect.

  • Synthesis and Properties of Fluoroazulenes. II. Electrophilic Fluorination of Azulenes with<i>N</i>-Fluoro Reagents

    日期:1996.6
    3-difluoroazulenes were synthesized for the first time by the electrophilic fluorination of azulenes with N-fluoro reagents. Selective preparation of 1-fluoroazulenes were performed by the fluorination of methyl azulene-1-carboxylates, followed by demethoxycarbonylation in 100% H3PO4. 2-Substituted azulenes were fluorinated in higher yields. In the 1H NMR of 1-fluoroazulene, long-range JFH values were
    1-氟-和1,3-二氟-和1,3-二氟-和1-二氟-和1,3-二氟- azulenes 是第一次通过用N-氟试剂对azulenes 进行亲电氟化来合成。1-氟丁烯的选择性制备是通过甲基 azulene-1-carboxylates 的氟化,然后在 100% H3PO4 中脱甲氧基羰基化来进行的。2-取代的芘以更高的产率被氟化。在 1-氟芴的 1H NMR 中,与 1-氟萘相比,在 H-2 和 H-8 处未观察到长程 JFH 值。由于所谓的 +Iπ 效应,1-氟原子会导致薁的可见光吸收发生显着的红移。
