摘要：

New complexes of lanthanide(III) triflates with polyethylene glycol (HO(CH2CH2O)(n)H; n=2, 3, 4) and polyethyleneglycol dimethylether (CH3O(CH2CH2O)(n)CH3; n=2, 3, 4) ligands have been prepared and characterised by X-ray diffraction. These complexes are effective Lewis acid catalysts for the allylation of aldehydes with allyltributyltin, and for the Diels-Alder reaction. Complexes with new homochiral podand ligands have been synthesised and in one case characterised by X-ray diffraction, and their catalytic activity is under investigation.
