• FeX₃-Promoted Intermolecular Addition of Benzylic Alcohols to Aromatic Alkynes: A Mild and Efficient Strategy for the Synthesis of Alkenyl Halides
  作者：Kai Ren、Min Wang、Lei Wang

  日期：2010.1

  A convenient, effective, mild and simple strategy has been developed for the synthesis of alkenyl halides by the intermolecular addition of benzylic alcohols to aromatic alkynes. The reactions were carried out in the presence of iron(III) bromide or chloride in 1,2-dibromoethane without additives in air at room temperature. Alkenyl bromides and chlorides were obtained with high regio- and stereoselectivity

  已经开发了一种方便、有效、温和且简单的策略，用于通过苄醇与芳炔的分子间加成来合成卤代烯。反应在溴化铁（III）或氯化铁的 1,2-二溴乙烷中，在室温空气中进行，无添加剂。在温和的反应条件下，在 0.5-1 小时内以高到极好的收率获得了具有高区域和立体选择性（E/Z 高达 99:1）的烯基溴化物和氯化物。

  A simple and efficient catalytic method for the synthesis of alkenyl halides via direct coupling of alcohols and alkynes using aqueous HX (X=Cl, Br) as halide sources has been developed under mild conditions in the presence of Fe powder (1 mol %). In comparison with the high loading of FeX3 in previously reported protocols, the present approach provides a remarkable attractive methodology to a diverse

  已经在温和的条件下，在铁粉（1摩尔％）存在的条件下，开发了一种简单高效的催化方法，该方法通过使用HX水溶液（X = Cl，Br）作为卤化物源，通过醇和炔烃的直接偶联来合成烯基卤化物。与以前报道的方案中FeX 3的高负载相比，由于操作简单和金属污染程度低的优点，本方法为各种范围的烯基卤化物提供了引人注目的有吸引力的方法。

  This work demonstrated an efficient and mild method for preparing various substituted alkenyl halides via direct C–C bond formation of benzyl alcohols and aryl alkynes in CH2Cl2 at 50 °C by using 50 mol % of FeCl3·6H2O or FeBr3. Compared with the systems using excessive boron trihalides and stoichiometric n-BuLi to prepare substituted alkenyl halides, the present procedure would provide an excellent

  simple, and straightforward one-pot reaction of alkynes with various alcohols in the presence of iron salts (FeCl3 and FeBr3) was described to yield the corresponding alkenyl halides with complete regioselectivity and highstereoselectivity. The reaction is high yielding and works under mild conditions. The iron salts act as Lewis acids and a source of halides. The reaction tolerates a wide variety of functional

  A stereo-selective reaction for the synthesis of cis-alkenes/halo-alkenes from diphenylmethane and ethynylbenzenes was developed in the presence of iron(III) bromide or chloride. Alkenyl bromides/chlorides were obtained in comparatively good yields in chlorobenzene under mild reaction conditions. (C) 2012 Elsevier Ltd. All rights reserved.
