An Unusual Hydrogen Migration/C−H Activation Reaction with Group 3 Metals
摘要:
A novel hydrogen migration from the phenyl ring to the pyridine ring of an yttrium pyridyl complex supported by a 1,1'-ferrocene diamide ligand is reported. Density functional theory calculations were instrumental in probing the mechanism for this transformation.

A new method for generating group3 metal complexes containing radical-anionic 2,2′-bipyridyl (bipy) ligands is described that relies on hydrogen-atom abstraction from dearomatized biheterocyclic complexes. This method does not involve electron transfer to neutral 2,2′-bipyridyl or salt metathesis between the lithium salt of the 2,2′-bipyridyl radical anion and group3 metal halides. The new metal
