The synthesis of 3-vinylindoles through Wadsworth Emmons reactions with 3-formyl and 3-acylindoles is described.Altough 3-formylindoles react directly with phosphonate derivatives, 3-acylindoles need prior activation by N-sulphonation. 11H-5-Cyanobenzocarbazole has been prepared by the oxidative cycloaddition of E-3-(indol-3'-yl) propenonitrile and benzyne.
