• Sequential bromination reactions from beads with methyltriphenylphosphonium tribromide groups
  作者：Rodrigo Cristiano、Andrew D. Walls、Richard G. Weiss

  DOI：10.1002/poc.1694

  日期：——

  A reusable bromination reagent based on polystyrene beads with covalently appended methyltriphenylphosphonium tribromide groups has been developed. The results from bromination reactions of several structurally diverse unsaturated substrates with the beads and with solutions of a non‐polymeric model brominating reagent, methyltriphenylphosphonium tribromide, are described. It is shown that the reactions

  ionic liquids (RTILs) comprised of a tetraalkylphosphonium cation (tridecylmethyphosphonium or trihexyltetradecylphosphonium) and a trihalide anion (Br3−, BrCl2−, or ClBr2−) have been prepared and characterized. Their ability to effect halogenation reactions with a variety of substrates has been explored. In general, halogenation reactions of alkenes proceed with high yields and stereo- and regioselectivities

  六室温离子液体（离子液体）包含四烷基鏻阳离子（tridecylmethyphosphonium或三己基十四）和三卤化阴离子的（BR 3 - ，氯化溴2 - ，或CLBR 2 -）已准备好并进行了特征化。已经探索了它们与多种底物进行卤化反应的能力。通常，无论在不存在或存在溶剂（氯仿）的情况下进行，烯烃的卤化反应都以高收率和立体选择性和区域选择性进行。还已经研究了炔烃和在芳环上的亲电子取代的反应。盐的简便制备，易于处理以及产物分离的简单性，应使这些RTIL成为卤化试剂库和特定转化选择试剂的有用补充。

• Stereoselective Bromination Reactions Using Tridecylmethylphosphonium Tribromide in a “Stacked” Reactor
  作者：Kefeng Ma、Shaw Li、Richard G. Weiss

  DOI：10.1021/ol801327n

  日期：2008.10.2

  A new reagent, tridecylmethylphosphonium tribromide, and new procedures for bromination reactions of unsaturated substrates (including one that allows several substrates to be reacted in sequence) are described. The procedures exploit the diffusion of components and the densities and immiscibilities of layers, including a fluorous "spacer" layer, within a reaction vessel. The stereoselectivities achieved in-the reactions are superior in some cases to those found with other brominating reagents.
