Abstract

original image

Liganden-Stehblues: In einem Dieisenkomplex mit unsymmetrischem Brückenligand wurde unerwartet das verbrückte Intermediat der Wanderung eines Phosphorliganden zwischen den beiden Metallzentren beobachtet. Der Prozess verläuft ähnlich wie die Wanderung eines Carbonylliganden, ist aber so langsam, dass er NMR-spektroskopisch untersucht werden kann.
