Abstract

The first neutral rare-earth metal dinuclear dihydrido complexes [(NPNPN)LnH₂]₂ (2-Ln; Ln = Y, Lu; NPNPN: N[Ph₂PNC₆H₃(ⁱPr)₂]₂) bearing μ₂-bridging hydride ligands have been synthesized. In the presence of THF, 2-Y undergoes intramolecular activation of the sp² C–H bond to form dinuclear aryl–hydride complex 3-Y containing three μ₂-bridging hydride ligands.
