Abstract
- Reaction of (C5Me5)Lu(CH2SiMe3)2(THF) with pyridine results in the activation of an ortho C−H bond to form the corresponding 2-(N,C)-pyridyl complex with elimination of SiMe4. This is a rare example of pyridine metalation at a lanthanide metal center in the absence of a bent metallocene framework. The 2-(N,C)-pyridyl coordination mode was confirmed by X-ray crystallographic analysis. The pyridyl complex adopts a distorted square-pyramid geometry with the C5Me5unit residing in the apical position and the pyridyl ligand and remaining ligands residing in the basal plane. Isotopic labeling studies suggest that C−H bond activation is consistent with a -bond metathesis mechanism. [ABSTRACT FROM AUTHOR]
