• Silyldefluorination of Fluoroarenes by Concerted Nucleophilic Aromatic Substitution
  作者：Shubhadip Mallick、Pan Xu、Ernst-Ulrich Würthwein、Armido Studer

  DOI：10.1002/anie.201808646

  日期：2019.1.2

  The reaction of readily generated silyl lithium reagents with various aryl fluorides to provide the corresponding aryl silanes is reported. DFT calculations reveal that the nucleophilic aromatic substitution of the fluoride anion by the silyl lithium reagent proceeds through concerted ipso substitution. In contrast to the classical nucleophilic aromatic substitution, this concerted ionic silyldefluorination

  据报道容易产生的甲硅烷基锂试剂与各种芳基氟化物反应以提供相应的芳基硅烷。DFT计算表明，甲硅烷基锂试剂对氟化物阴离子的亲核芳香族取代是通过协同的ipso取代进行的。与经典的亲核芳香族取代相反，这种协同的离子化甲硅烷基脱氟反应也发生在电子含量更高的芳基氟化物上。
