Abstract

N₂ shuffle: One-electron reduction of the ansa-zirconocene complex with a side-on dinitrogen ligand furnished the corresponding anion in which the hapticity of the N₂ ligand changed to end-on. Oxidation of the anion regenerates the neutral complex with concomitant change in N ₂ hapticity. The zirconocene complexes with unusual (N ₂)^3-/(N₂)^- ligands have been fully characterized. Ad=adamantyl.
