Examples of 2,2′-, 2,3′-, and 2,7′-biindolyls have been prepared by the reaction of indoles with indolin-2-ones and phosphoryl chloride or trifluoromethanesulfonicanhydride. In certain conditions terindolyls can also be formed and those described contain combinations of the above linkages.

Regioselective reactions of 3-substituted 4,6-dimethoxybenzofurans with indolin-2-ones and triflic anhydride afforded 7- and/or 2-substituted indolo-benzofurans and the latter were cyclised to previously unknown benzofuran-fused benzocarbazoles using palladium (II) acetate in heated acetic acid.

Various substituted indoles undergo electrophilic substitution with indolin -2-one or 4,6-dimethoxyindolin-2-one and phosphoryl chloride to afford 2,2′-,2,3′-,or2,7′-bi-indolyls, depending on the initial substitution pattern.
