available stable radical cation triarylaminium salt can be used as an efficient initiator for Friedel–Craftsreaction of indoles with enamides to regioselectively construct complex indole derivatives and for double Friedel–Craftsreaction 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
