The reaction of electron-rich 3-aryl-substituted 4,6-dimethoxyindoles in the presence of base with triflic anhydride results in biaryl coupling, producing both 2,2 0 -and 2,7 0 -biindoles. Further, if acetone is present, the corresponding vinyl triflate is formed and subsequent reaction yields the k
