On heating bis(2,6-dichlorophenyl)ethylenediamines 1a-d give indoles and - in the case of the racemates 1b and d - tetrahydroindoloindoles.The d,l-form of the corresponding 2,4-dichloro compound 1f leads to a 2,4,5-triarylimidazolidine, the meso-form 1e to an aziridine, whose formation via a 2,cis-4,5-triarylimidazolidine appears likely from mechanistic considerations.
