  Synthesis and properties of novel fluoroionophores for Ag+-optode sensing based on oligophenylenevinylenes

  摘要：

  Novel hexylsulfanyl substituted oligophenylenevinylenes have been designed and synthesized as fluoroionophores which selectively detect Ag+ ions in membrane optode sensors. In addition, the 4-phenyl-ring oligomer-based optode sensor exhibits higher sensitivity than that of the 3-phenyl-ring counterpart. (C) 2000 Elsevier Science Ltd. All rights reserved.

• Synthesis of oleophilic electron-rich phenylhydrazines
  作者：Aleksandra Jankowiak、Piotr Kaszyński

  DOI：10.3762/bjoc.8.29

  日期：——

  Phenylhydrazines 1 substituted with two or three long-chain alkyl, alkoxy or alkylsulfanyl groups were successfully prepared by acid-induced removal of the Boc group in hydrazides 2. The reaction is carried out with 5 equivalents of TfOH in CF₃CH₂OH/CH₂Cl₂ at −40 °C for 1.5 min. Under these conditions, the deprotected hydrazine 1 is fully protonated, which increases its stability in the reaction medium. The hydrazines were isolated in 60–86% yields and purities >90%. The hydrazides 2 were obtained in 43–71% yields from aryl bromides 5, which were lithiated with t-BuLi and subsequently reacted with di-tert-butyl azodicarboxylate (DTBAD).

  苯基肼1通过酸诱导去除肼酰胺2中的Boc基团，成功地取代了两个或三个长链烷基、烷氧基或烷基硫基团。反应在CF₃CH₂OH/CH₂Cl_{2>中以5当量的TfOH在-40°C下进行1.5分钟。在这些条件下，去保护的肼1被完全质子化，增加了其在反应介质中的稳定性。肼类产物以60-86%的产率和纯度>90%的纯度分离。肼酰胺2以43-71%的产率从芳基溴化物5中获得，该溴化物通过与t-BuLi锂化，然后与双tert-丁基叠氮二羧酸酯（DTBAD）反应得到。}

  3,4-Dialkylsulfanyl- (1a[n], n = 8, 9, 11) and 3,4,5-trialkylsulfanylbromobenzenes (1b[n], n = 6, 8, 10, 12) were prepared from 3,4-difluoro- and 3,4,5-trifluorobromobenzene, respectively, in 50-60% yields. The bromobenzenes 1[n] were converted to benzaldehydes 2[n] by lithium-halogen exchange followed by reaction with DMF.[GRAPHICS].

  Substitution of the 1,3,5-triphenyl-6-oxoverdazyl radical with n-alkylsulfanyl groups lead to derivatives 1[n], which exhibit a columnar rectangular phase (Col(r) ) below 60 degrees C. Compounds 1[n] have a broad absorption band in the visible region with maxima at 540 and 610nm and redox potentials E0/+1 (1/2) = +0.99V and E0/-1 (1/2) = -0.45V vs. SCE. Time-of-flight (TOF) investigation of 1[8] revealed hole mobility of (h) = 1.52 x 10(-3) cm(2) V-1 s(-1) in the columnar phase with an activation energy E-a = 0.06 +/- 0.01eV. Magnetization studies of 1[8] demonstrated nearly ideal paramagnetic behavior in both solid and fluid phases above 200K and weak antiferromagnetic interactions at low temperatures. Verdazyl derivatives 1[n] were prepared in a sequence of reactions starting from 1-bromo-3,4,5-trifluorobenzene by alkylsulfanylation, followed by hydrazinylation, and finally 6-oxoverdazyl ring assembly using the Milcent method.
