Reactions of triguanidinate lanthanide complexes Ln[(iPrN)(NC6H4p-Cl)C(NHiPr)]3 (Ln = Nd, Y) with 3 equiv. of n-BuLi gave [Li(THF)(DME)]3Ln[μ-η2η1 (iPrN)2C(NC6H4p-Cl)]3, which represents the first structurally characterized complexes of lanthanide and lithium metals with dianionic guanidinate ligands. The Nd complex was found to be an effective catalyst for amidation of aldehydes with amines under mild conditions with a wide scope of substrates.
Graphical abstractThe first heterobimetallic complexes of lanthanide and lithium metals with dianionic guanidinate ligands [Li(THF)(DME)]3Ln[μ-η2η1 (iPrN)2C(NC6H4p-Cl)]3 (Ln = Nd and Y) were synthesized and fully characterized. The Nd complex was found to be an efficient catalyst for amidation of aldehydes with amines under mild conditions with a wide scope of substrates including pyrrolidine, piperidine and morpholine.Figure optionsDownload full-size imageDownload as PowerPoint slide
