• Manganese(iii) acetate mediated radical reactions in the presence of an ionic liquid
  作者：Gregory Bar、Andrew F. Parsons、C. Barry Thomas

  DOI：10.1039/b103544b

  日期：——

  A new, mild and practical method for conducting manganese(III)-mediated radical reactions, which lead to the formation of carbon–carbon bonds, has been developed using the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]).

  利用离子液体 1-丁基-3-甲基咪唑四氟硼酸盐（[bmim][BF4]），我们开发出了一种新的、温和而实用的方法，用于进行锰（III）介导的自由基反应，从而形成碳-碳键。

  The one-pot, three-component reactions of substituted 1,3-cyclohexanediones, iodobenzene diacetate and alkenes, under photochemical activation, yields fused dihydrofuran derivatives in good yield via the in situ formation of iodonium ylides. (C) 2012 Elsevier Ltd. All rights reserved.
• Metal-Catalyzed Thermal Reactions of Cyclic β-Dicarbonyl Phenyliodonium Ylide with Styrenes
  作者：Alexandra-Eleni Bosnidou、Dimitra Kalpogiannaki、Sofia Karanestora、John A. Nixas、Lazaros P. Hadjiarapoglou

  DOI：10.1021/jo502611x

  日期：2015.1.16

  A cyclic beta-dicarbonyl phenyliodonium ylide reacted with various substituted styrenes under Rh-2(OAc)(4) catalysis to give cyclopropanes and dihydrofurans in a highly regioselective fashion. When styrenes with electron-donating substituents or disubstituted were employed, only dihydrofurans were isolated instead. A mechanism involving two competing pathways rationalizes the results.
• Potassium Persulfate Mediated Oxidative Radical Cyclization of 1,3-Dicarbonyl Compounds with Styrenes for the Synthesis of Dihydrofurans
  作者：Li-Na Guo、Shun Wang、Lin-Ye He

  DOI：10.1055/s-0034-1378806

  日期：——

  A potassium persulfate promoted tandem radical addition/cyclization of 1,3-dicarbonyl compounds with styrenes has been developed. This transition-metal-free procedure provides an efficient approach to a diverse set of substituted dihydrofurans in moderate to good yields.
