Yttrium dialkyl complexes coordinated by 6-aryl-substituted amidopyridinate ligands undergo selective intramolecular sp(2) or sp(3) C-H bond activation. Upon treatment with PhSiH(3) of the resulting Y-C(alkyl, aryl) or Y-C(alkyl,benzyl) systems, a a-bond metathesis reaction takes place selectively at the Y-C(alkyl) bond, generating rare dimeric aryl-hydrido or benzyl-hydrido yttrium complexes, respectively.
