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
这项工作证明了一种有效而温和的方法,可通过使用50 mol%的FeCl 3 ·6H 2 O或FeBr通过在50°C下在CH 2 Cl 2中直接形成苄醇和芳基炔烃的C–C键形成各种取代的烯基卤化物。3。与使用过量的三卤化硼和化学计量的n- BuLi制备取代的烯基卤化物的系统相比,由于对环境有益的系统和原子效率,本方法将提供极好的替代方法。
