  双（环戊二烯基铁）芳烃配合物：合成和官能化聚芳醚的新途径

  摘要：

  A new development in the chemistry of arenes activated toward S(N)Ar reactions by the cyclopentadienyliron (FeCp+) moiety is presented in this work. A class of diiron complexes of diphenoxybenzenes was prepared in a highly efficient and very mild fashion. Dihydroxyaromatic compounds served as dinucleophiles, allowing for the formation of the diiron complexes. This could be achieved in either a one or two step procedure. A wide variety of dinucleophiles were incorporated into this study, as well as a number of FeCp+ activated arenes. It is shown that these reactions are not inhibited by bulky substituents on either the dinucleophiles or activated arenes. The diiron complexes themselves could also undergo S(N)Ar reactions, provided that the complexed arenes contained a chlorine substituent. This allowed for the functionalization of the complexes with species that could not be introduced directly in their syntheses. The carbon nucleophiles generated from ethyl cyanoacetate or (phenylsulfonyl)acetonitrile could be attached to the complexed ethers in this manner. The FeCp+ moieties were removed easily by photolytic demetalation which allowed for the recovery of a wide range of functionalized diphenoxybenzenes. This methodology is advantageous over all those previously reported and should be a practical route to the synthesis of aromatic ethers.

  A phthalide compound of general formula (I) and a near infrared absorber and a recording material each utilizing the phthalide compound are disclosed. wherein ring A represents a substituent group of the following formula    where R₁ represents hydrogen, alkyl, alkoxy or halogen; n represents an integer of 1-3; ring B represents a defined aromatic ring; R₂ represents alkyl or aryl; R₃ represents alkyl; R₄ and R₅ independently represent alkyl or unsubstituted or substituted phenyl; R₆ represents hydrogen, alkyl or alkoxy. The near infrared absorber and the recorded image on the recording material absorb strongly the near infrared region with no appreciable absorption in the visible region of the spectrum. The near infrared absorber is colorless or pale in color and yet highly capable of absorbing near infrared radiation. The recorded image on the recording material can hardly be read with the eye but can be read with the OCR. Moreover, the effect on the developed shade of any concomitant color former in a recording material is minimal.

  本发明公开了通式（I）的邻苯二甲酸盐化合物以及利用该邻苯二甲酸盐化合物的近红外吸收剂和记录材料。 其中环 A 代表下式的取代基团 其中 R₁ 代表氢、烷基、烷氧基或卤素；n 代表 1-3 的整数；环 B 代表确定的芳环；R₂ 代表烷基或芳基；R₃ 代表烷基；R₄ 和 R₅ 独立地代表烷基或未取代或取代的苯基；R₆ 代表氢、烷基或烷氧基。 近红外吸收体和记录材料上记录的图像对近红外区域有强烈的吸收，而对光谱的可见光区域没有明显的吸收。近红外吸收体是无色或浅色的，但吸收近红外辐射的能力很强。记录材料上记录的图像几乎无法用肉眼读取，但可以用 OCR 读取。此外，记录材料中的任何伴色前者对显影色调的影响微乎其微。
• Selective displacement of aryl fluorides with hydroquinone: synthesis of 4-phenoxyphenols

  The selective displacement of a variety of aryl fluorides with hydroquinone has been achieved to give substituted 4-phenoxyphenols 3. In some cases the addition of 18-crown-6 resulted in a significant rate enhancement, and the reactions could be carried out at lower temperature. One of these derivatives, 3a (X = Cl) was converted to 2-propyl-4-(4-chlorophenoxy)phenol 2a, a precursor to the PPAR gamma receptor agonist 1. (c) 2005 Elsevier Ltd. All rights reserved.
