• Environmentally benign electrophilic and radical bromination ‘on water’: H2O2–HBr system versus N-bromosuccinimide
  作者：Ajda Podgoršek、Stojan Stavber、Marko Zupan、Jernej Iskra

  日期：2009.5

  brominating systems reveals the H2O2–HBr system to be more reactive than NBS for benzyl bromination and for the bromination of ketones, while for electrophilic aromatic substitution of methoxy-substituted tetralone it was higher for NBS. Also, higher yields of brominated aromatics were observed when using H2O2–HBr ‘on water’. Bromination of styrene reveals that not just the structure of the brominating reagent

  AH 2 O 2 -HBr系统和N-溴琥珀酰亚胺在水性介质中被用作亲电和自由基溴化的“绿色”方法。使用两种体系，在环境温度下且不添加金属或酸催化剂的情况下，几种活化和活化程度较低的芳族分子，苯基取代的酮和苯乙烯都可以在水中“有效”溴化，而各种未活化的甲苯则在存在可见光作为自由基活化剂。两种溴化系统的反应性和选择性的比较表明，H 2 O 2-HBr系统在苄基溴化和酮的溴化方面比NBS具有更高的反应性，而对于甲氧基取代的四氢萘酮的亲电芳香取代，NBS则更高。另外，使用H 2 O 2时，溴化芳烃的收率更高。–HBr“上水”。苯乙烯的溴化揭示了不仅溴化试剂的结构，而且反应条件：水量，有机溶剂，搅拌速率和界面结构也对定义溴化的结果（二溴化与溴羟基化）起着关键作用。此外，温和的反应条件，简单的分离程序，廉价的试剂以及对环境的较低影响，使得水性溴化方法可以替代其他已报道的溴化方法。
• A Scalable Procedure for Light-Induced Benzylic Brominations in Continuous Flow
  作者：David Cantillo、Oscar de Frutos、Juan A. Rincon、Carlos Mateos、C. Oliver Kappe

  DOI：10.1021/jo402409k

  日期：2014.1.3

  A continuous-flow protocol for the bromination of benzylic compounds with N-bromosuccinimide (NBS) is presented. The radical reactions were activated with a readily available household compact fluorescent lamp (CFL) using a simple flow reactor design based on transparent fluorinated ethylene polymer (FEP) tubing. All of the reactions were carried out using acetonitrile as the solvent, thus avoiding

  提出了使用N-溴代琥珀酰亚胺（NBS）溴化苄基化合物的连续流程方案。使用基于透明氟化乙烯聚合物（FEP）管的简单流式反应器设计，使用易于获得的家用紧凑型荧光灯（CFL）激活自由基反应。所有反应均使用乙腈作为溶剂进行，从而避免使用有害的氯化溶剂，例如CCl 4。对于每种底物，仅需要1.05当量的NBS即可将苄基原料完全转化为相应的溴化物。通过溴化一组包含不同官能团的19种底物，证明了该方法的一般特征。在所有情况下均获得了良好的分离效果。通过使反应器运行更长的时间（吞吐量为30 mmol h –1），可以很容易地将新的流量规程缩放到几克数量，这在分批光化学反应器中不容易实现。溴化方案也可以在更大流量的反应器中使用功率更大的灯以相同的效率执行。以苯丙酮溴化为模型，所需溴化物的产率为180 mmol h –1。

• Solvent free, light induced 1,2-bromine shift reaction of α-bromo ketones
  作者：Sejin An、Da Yoon Moon、Bong Ser Park

  DOI：10.1016/j.tet.2018.10.015

  日期：2018.11

  good product selectivity, which can be coined as 1,2-Br shift reaction. The product selectivity increases when the reaction is done in neat or solid state, where only the 1,2-Br shift product is formed in some cases. The reaction is suggested to proceed by CBr bond homolysis to give a radical pair, followed by disproportionation and conjugate addition of HBr to the α,β-unsaturated ketone intermediate

  α-溴苯乙酮在乙腈中的光解作用导致形成了具有良好产物选择性的β-溴苯乙酮，这可以被称为1,2-Br转移反应。当反应以纯净或固态进行时，产物选择性增加，在某些情况下，仅形成1,2-Br转移产物。建议反应由C进行Br键均质化，得到一个自由基对，然后歧化和将HBr共轭添加到α，β-不饱和酮中间体上。当不饱和中间体通过额外的共轭作用稳定时，反应在不饱和酮成为主要产物的阶段停止。由于该反应不使用挥发性有机溶剂和任何其他添加剂（例如酸，碱或金属催化剂等），因此该研究中描述的合成方法很好地适合于生态友好型有机合成。此外，该方法还适用于完美原子经济，不会产生任何副产品。合成方法应比其他替代方法有更多优势，以获得β-溴代羰基化合物。
