  Yttrium‐Amidopyridinate Complexes: Synthesis and Characterization of Yttrium‐Alkyl and Yttrium‐Hydrido Derivatives

  摘要：

  AbstractAryl‐ or heteroaryl‐substituted aminopyridine ligands (N2HAr) react with an equimolar amount of [Y(CH2SiMe3)3(thf)2] to give yttrium(III)‐monoalkyl complexes. The process involves the deprotonation of N2HAr by a yttrium alkyl followed by a rapid and quantitative intramolecular sp2‐CH bond activation of the aryl or heteroaryl pyridine substituents. As a result, new Y complexes distinguished by rare examples of CH bond activations have been isolated and completely characterized. Selective σ‐bond metathesis reactions take place on the residual Y–alkyl bonds upon treatment with PhSiH3. Unusual binuclear metallacyclic yttrium(III)‐hydrido complexes have been obtained and characterized by NMR spectroscopy and X‐ray diffraction analysis.
