• A New Alkylation of Aryl Alcohols by Boron Trifluoride Etherate
  作者：Ndze Denis Jumbam、Yamkela Maganga、Wayiza Masamba、Nomthandazo I. Mbunye、Esethu Mgoqi、Sphumusa Mtwa

  DOI：10.3390/molecules24203720

  日期：——

  The ethylation of aryl alcohols by an ethyl moiety of boron trifluoride etherate is described. The reaction proceeded cleanly and afforded good yields of the corresponding aryl ethyl ethers. It tolerated the presence of functional groups such as aryl, alkyl, halogens, nitro, nitrile, and amino. However, the presence of amino or nitro groups ortho to a hydroxyl group of an aryl compound drastically

  描述了芳醇被三氟化硼醚合物的乙基部分的乙基化。反应顺利进行并提供了相应芳基乙基醚的良好收率。它容忍官能团的存在，例如芳基、烷基、卤素、硝基、腈和氨基。然而，由于上述官能团与三氟化硼醚合物的螯合，芳基化合物羟基邻位的氨基或硝基的存在大大降低了预期产物的产率。芳环系统中的氮原子，例如羟基吡啶和 8-羟基喹啉，完全抑制了反应。间苯二酚、氢醌和具有醛官能团的芳醇在反应条件下分解。
