A new method has been achieved to synthesize indoletrimers 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.

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.

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.
