Abstract

original image

Ein Ruthenium-Carben-Komplex dient als Stoppergruppe in einem [2]Rotaxan, das als Intermediat bei der Synthese Porphyrin-haltiger [3]Rotaxane durch Olefinmetathese auftritt. Die Rotaxan-Achse lässt sich durch Ringöffnungsmetathese-Polymerisation mit Cyclooctadien um einiges verlängern (siehe Bild).
