Yttrium dialkyl complexes coordinated by 6-aryl-substituted amidopyridinate ligands undergo selective intramolecular sp2 or sp3 C-H bond activation. Upon treatment with PhSiH3 of the resulting Y-C(alkyl, aryl) or Y-C(alkyl,benzyl) systems, a ?-bond metathesis reaction takes place selectively at the Y-C(alkyl) bond, generating rare dimeric aryl-hydrido or benzyl-hydrido yttrium complexes, respectively.

Abstract
Yttrium dialkyl complexes coordinated by 6-aryl-substituted amidopyridinate ligands undergo selective intramolecular sp2 or sp3 C-H bond activation. Upon treatment with PhSiH3 of the resulting Y-C(alkyl, aryl) or Y-C(alkyl,benzyl) systems, a ?-bond metathesis reaction takes place selectively at the Y-C(alkyl) bond, generating rare dimeric aryl-hydrido or benzyl-hydrido yttrium complexes, respectively.File in questo prodotto:
