  • The Reaction of 2-Chloroazulene Derivatives with Lithium Acetylide in Liquid Ammonia
    作者:Tadayoshi Morita、Taira Fujita、Kahei Takase
    DOI:10.1246/bcsj.53.1647
    日期:1980.6
    The reaction of diethyl 2-chloroazulene-1,3-dicarboxylate (1a) with lithium acetylide in liq ammonia gave diethyl 4- and 6-ethynylazulene-1,3-dicarboxylates by an abnormal substitution reaction. In a similar manner, some 2-chloroazulenes, possessing alkoxycarbonyl and/or cyano substituents at the 1- and 3-positions of azulene nucleus, gave the corresponding 4 (or 8)- and 6-ethynylazulenes. The same
    2-脒-1,3-二羧酸乙酯(1a)与乙炔氨水中反应,通过异常取代反应得到4-和6-乙炔基-1,3-二羧酸乙酯。以类似的方式,一些在 azulene 核的 1- 和 3- 位具有烷氧基羰基和/或基取代基的 2-,得到相应的 4(或 8) - 和 6- 乙炔。当苯乙炔用作试剂时,进行相同类型的反应,1a 得到二乙基 4-和 6-(苯乙炔基)-、6-(3-基)-和 6-(9-基) )azulene-1,3-dicarboxylates,分别。
  • Synthesis of Poly(6-azulenylethynyl)benzene Derivatives as a Multielectron Redox System with Liquid Crystalline Behavior

    cyclic voltammetry (CV), which revealed the presumed multielectron redox properties. Compound 4b exhibited a one-step, two-electron reduction wave upon CV, which revealed the formation of the dianion stabilized by two 6-azulenylethynyl substituents under electrochemical reduction conditions. Four 6-azulenylethynyl substituents on a benzene ring in a 1,2,4,5 relationship increased the electron-accepting properties
    一系列聚(6-azulenylethynyl)苯在 azulene 环的 1,3-位被正己氧羰基链取代,即六-、1,2,4,5-四-、1,3,5-三-和 1,4-双 (6-azulenylethynyl) 苯衍生物 1、2、3 和 4b,通过简单的一锅反应制备,包括重复 Pd 催化的卤代芳烃与取代的 6-乙炔和/或在 Sonogashira-Hagihara 条件下,乙炔芳烃与取代的 6-甘菊烯。这些新型聚 (6-azulenylethynyl) 苯衍生物的氧化还原行为通过循环伏安法 (CV) 进行了检查,揭示了假定的多电子氧化还原特性。化合物 4b 在 CV 上表现出一步两电子还原波,这揭示了在电化学还原条件下由两个 6-azulenylethynyl 取代基稳定的二价阴离子的形成。由于形成稳定的闭壳双阴离子结构,苯环上的四个 6-azulenylethynyl 取代基以 1,2
  • Diels–Alder approach to the synthesis of azulene-substituted benzene derivatives. Synthesis and redox behavior of 1,2-di(6-azulenyl)tetraphenylbenzenes

    DOI:10.1016/s0040-4039(00)01445-3
    日期:2000.10
    1,2-Di(6-azulenyl)tetraphenylbenzenes and (6-azulenyl)pentaphenylbenzenes were synthesized by Diels-Alder reaction of di(6-azulenyl)acetylenes and 6-(phenylethynyl)azulenes with tetraphenylcyclopentadienone. Mono(6-azulenyl)benzenes exhibited a reduction wave upon cyclic voltammetry (CV). In contrast to the benzene derivatives, di(6-azulenyl)benzenes showed a two-step reduction wave at similar potential region upon CV, which revealed the formation of dianions stabilized by 6-azulenyl substituents under electrochemical reduction conditions.

  • Synthesis and Redox Behavior of Azulene-Substituted Benzene Derivatives and (η<sup>5</sup>-Cyclopentadienyl)[tetra- and di(6-azulenyl)cyclobutadiene]cobalt Complexes
    作者:Shunji Ito、Haruki Inabe、Tetsuo Okujima、Noboru Morita、Masataka Watanabe、Nobuyuki Harada、Kimiaki Imafuku
    DOI:10.1021/jo010540u
    日期:2001.10.1
    1,2-Di(6-azulenyl)tetraphenylbenzenes and (6-azulenyl)pentaphenylbenzenes were synthesized by Diels-Alder reactions of di(6-azulenyl)acetylenes and 6-(phenylethynyl)azulenes with tetraphenylcyclopentadienone. Cobalt-mediated cyclooligomerization of mono- and di(6-azulenyl)acetylenes afforded 1,3,5- and 1,2,4-tri(6-azulenyl)benzene derivatives together with (eta (5)-cyclopentadienyl)[tetra- and di(6-azulenyl)cyclobutadiene] cobalt complexes. The redox behavior of these novel (6-azulenyl)benzene derivatives and [tetra- and di(6-azulenyl)cyclobutadiene] cobalt complexes was examined by cyclic voltammetry (CV). Mono(6-azulenyl)benzenes exhibited a reduction wave upon CV. In contrast, 1,2-di(6-azulenyl)benzenes showed a two-step reduction wave at the similar potential region upon CV, which revealed the formation of a dianion stabilized by 6-azulenyl substituents under electrochemical reduction conditions. Three 6-azulenyl substituents on benzene in a 1,2,4 relationship also increased electron-accepting properties because of the formation of a closed-shell dianionic structure, whereas 1,3,5-tri(6-azulenyl)benzenes were reduced stepwise.
