  Synthesis of C1-Substituted Oxabenzonorbornadienes

  摘要：

  Oxabenzonorbornadienes are valuable synthetic intermediates because they can serve as a general template with which to create highly substituted ring systems. However, to date, only very few C1-substituted oxabenzonorbornadienes have been reported. In this study, the synthesis of some C1-substituted oxabenzonorbornadienes was achieved by the Diels-Alder reaction between 2-substituted furans and benzyne. Moderate to good yields (16-80%) of the Diels-Alder reactions were observed. These C1-substituted oxabenzonorbornadienes will find applications as valuable synthetic intermediates and should be useful in studies of transition-metal-catalyzed reactions.

  摘要：

  A magnetically isolable iron oxide nanoparticles is introduced as an efficient heterogeneous photocatalyst for non‐directed C‒H arylation employing aryl diazonium salts as the aryl precursors. This first‐row transition metal‐based photocatalyst revealed versatile activities and is applicable to a wide range of substrates, demonstrating brilliant efficacy and superior recyclability. Detailed catalytic characterization describes the physical properties and redox behavior of the Fe‐catalyst. Adequate control experiments helped to establish the radical‐based mechanism for the C‒H arylation.

• Reaction of aryl triflates with heteroaryllithiums via aryne intermediates
  作者：Kelly Hardee Reuter、William J. Scott

  DOI：10.1021/jo00069a041

  日期：1993.8

  Unhindered aryl triflates react with a mixture of 1.5 equiv of LDA and 8-10 equiv of 2-lithiofuran at -78-degrees-C to form 2-arylfurans in 50-60% yield via the corresponding arynes. Regioisomeric ratios of products are similar to those observed for reactions of arynes with well-precedented nucleophiles, such as metal amides. Steric hindrance ortho to the triflate increases the cine to ipso ratio, but lowers overall yields due to enhanced nucleophilic attack at sulfur leading to formation of the corresponding phenol. Use of 2-lithiothiophene affords the analogous arylthiophene.
• Synthesis and Spectrokinetic Studies of a New Family of Dimethyl [2<i>H</i>]-Chromenes: Dimethyl 6-Aryl-2,2Dimethyl-[2<i>H</i>]-Chromene-7,8-Dicarboxylates
  作者：Alain Maggiani、Arlette Tubul、Pierre Brun、André Samat

  DOI：10.1080/10587250008023846

  日期：2000.6.1

  The synthesis of a series of dimethyl 6-aryl-2,2-dimethyl-[2H]-chromene-7,8-dicarboxylates is described. The photochromic properties of this new family of dimethyl-[2H]-chromenes have been studied in solution, under continuous irradiation. The presence of the methoxycarbonyl groups was shown to stabilise the coloured forms. The fading rates are generally low in comparison with the standard "naked" chromenes in the same experimental conditions. This stabilisation depends on the solvent used. We could observe the presence of one permanent opened form. Moreover, it seems that the synthesised molecules have a strong resistance toward photodegradation.
