Notizen: Abstract The reaction of 2-dicyanomethyleneindan-1,3-dione with pyrrole, indole, and their methyl derivatives gives products of addition at the dicyanomethylene carbon atom, viz., pyrrolyl- and indolyl(1,3-dioxo-2-indanyl)malononitriles, which upon heating or irradiation with UV light irreversibly split out HCN to give deeply colored products of replacement of the nitrile group in the acceptor by a heterocyclic grouping. Data from the UV and PMR spectra of the compounds obtained are presented.
