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 trifluoromethanesulfonic anhydride. In certain conditions terindolyls can also be formed and those described contained combinations of the above linkages.

A new method has been achieved to synthesize indole trimers and tetramers starting from indoles and 3-bromoindoles.Unusual open and cyclic trimers have been isolated and characterized, and the mechanism of formation is proposed.
A General Strategy for the Synthesis of 2,2'-, 2,3'-, and 2,7'-Bi-indolyls

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'-, or 2,7'-bi-indolyls, depending on the initial substitution pattern.
