Abstract

original image

Dem Ruhekomplex auf der Spur: [{IrCp*Cl2}2] katalysiert die Redoxcyclisierung von Nitronalkinen wie 1 unter Bildung von Azomethinyliden, die anschließend mit Elektrophilen und π-Bindungen umgesetzt werden können. Der ungewöhnliche O-gebundene Azomethinkomplex 2 wurde isoliert und als Ruhezustand des Katalysators in der Azomethinylid-Bildung identifiziert. Cp*=C5Me5.
