摘要：
Remove-Al: Organolanthanide complexes with anionic ligands derived from bis-(imino)pyridine give insight into organoaluminum-mediated alkylation of the ligand backbone and self-complexation. In addition, they provide structural evidence of the elusive η1 coordination mode in {Ln(μ-Me)AlMe3} (see picture). (Chemical Equation Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
