Abstract

Als neue Diinkomponente stellten wir das 2‐Phenyläthinyl‐1‐[3‐phenyl‐propin‐(2)‐yl]‐benzimidazol (1) her, in dem eine Acetylengruppe an einem sp^3^‐, die andere an einem sp^2^‐C‐Atom haftet. Man erhält mit Tris(triphenylphosphin)‐rhodiumchlorid leicht einen Komplex (3), dessen Umsetzung mit Acetylenen, Chalkogenen sowie Kohlenmonoxid zu den in der Überschrift genannten, zumeist noch unbekannten Heterocyclen 4–8 führt.
