  • Direct sustainable bromination of alkenes in aqueous media and basic ionic liquids
    作者:Patrizia Primerano、Massimiliano Cordaro、Angela Scala
    DOI:10.1016/j.tetlet.2013.05.097
    日期:2013.7
    Electron-rich and electron-poor alkenes have been dibrominated using a rapid and sustainable procedure. The reactions were conducted in aqueous medium and basic ionic liquids which catalyzed the direct addition of bromine. The protocol leads to remarkable results, high yields under mild conditions, complete chemo- and stereo-selectivity and allows the recycling of ionic liquids, reducing costs, and

  • Facile and Efficient Method for the Debromination of<i>vic</i>-Dibromides to Alkenes with BiCl<sub>3</sub>/Ga System
    作者:Byung Woo Yoo、Seo Hee Kim、Young Kwang Park
    DOI:10.1080/00397911.2010.542568
    日期:2012.6
    Abstract BiCl3/Ga was found to be a mild, efficient, and chemoselective system for the debromination of a series of functionally and structurally various vic-dibromides. A broad range of functional groups (ester, carboxy, aldehyde, methoxy, chloro, and ketone) was tolerated under the reaction conditions and only trans olefins were obtained in good yields. GRAPHICAL ABSTRACT
    摘要 BiCl3/Ga 被发现是一种温和、高效且具有化学选择性的体系,可用于一系列功能和结构不同的 vic-二溴化物的脱溴。在反应条件下可以容忍广泛的官能团(酯、羧基、醛、甲氧基、氯和酮),并且仅以良好的产率获得反式烯烃。图形概要
  • Visible-Light Photoredox Catalysis: Dehalogenation of Vicinal Dibromo-, α-Halo-, and α,α-Dibromocarbonyl Compounds
    作者:Tapan Maji、Ananta Karmakar、Oliver Reiser
    DOI:10.1021/jo102239x
    日期:2011.1.21
    vic-Dibromo-, α-halo-, or α,α-dibromocarbonyl compounds can be efficiently dehalogenated using catalytic tris(2,2′-bipyridyl)ruthenium dichloride (Ru(bpy)3Cl2) in combination with 1,5-dimethoxynaphthalene (DMN) and ascorbate as sacrificial electron donor. For this process, a visible light promoted photocatalytic cycle is proposed that involves the reduction of carbon halogen bonds via free radical
    使用催化三氯化三(2,2'-联吡啶基)钌(Ru(bpy)3 Cl 2)与1,5-结合可以有效地使vic -Dibromo-,α-卤代或α,α-二溴代羰基化合物脱卤二甲氧基萘(DMN)和抗坏血酸盐作为牺牲电子给体。对于该方法,提出了可见光促进的光催化循环,该循环涉及通过自由基中间体还原碳卤键。

    Sodium selenite catalyses, under mild conditions, the reductive debromination of vic-dibromides [e.g., meso- or (±)-1,2-dibromo-1,2-diphenylethane, trans-10,11-dibromodibenzosuberone, 2,3-dibromo-1,3-Biphenyl-1-propanone, α,β-dibromobenzenepropanoic acid, and cholesterol dibromide] to alkenes in the presence of the thiols cysteine or glutathione.

  • Rapid and Efficient Debromination of vic-Dibromides with VCl<sub>3</sub>/Indium System
    作者:Woo Yoo, Byung、Yeon Park, Jee、Jong Shin, Hyo
    DOI:10.5012/jkcs.2018.62.4.275
    日期:——
    The $VCl_3$/In system was found to be a new protocol for debromination of a variety of vic-dibromides to the corresponding alkenes in high yields with short reaction times under mild conditions. This new methodology is highly chemoselective, tolerating several functional groups such as chloro, bromo, fluoro, keto, ester, carboxyl, and methoxy groups.
