available stable radical cation triarylaminium salt can be used as an efficient initiator for Friedel–Crafts reaction of indoles with enamides to regioselectively construct complex indole derivatives and for double Friedel–Crafts reaction of indoles with vinyl ethers to offer 3,3′-Bis(indolyl)alkane derivatives. The ready availability of the starting materials and the usefulness of the products make this
市售的稳定自由基阳离子三芳基铵盐可以用作吲哚与酰胺类化合物的Friedel-Crafts反应以选择性地构建复杂的吲哚衍生物的有效引发剂,以及吲哚与乙烯基醚的双重Friedel-Crafts反应以提供3,3'-Bis()的有效引发剂。吲哚基)烷烃衍生物。起始材料的随时可用和产品的实用性使该策略具有吸引力。
