摘要：

The ytterbium(III) and yttrium(III) bis(trifluoromethanesulfonyl) amide complexes (la and Ib) have been synthesized from the corresponding metal oxides and 3 equiv. of bis( trifluoromethanesulfonyl) imide in refluxing water, as highly effective catalysts for the Diels-Alder reaction. The X-ray crystal analysis of the ytterbium(III) bis( trifluoromethanesulfonyl)amide complex with N, N'-dimethylpropyleneurea (2a) recrystallized from N,N'-dimethylpropyleneurea and ethyl acetate reveals the mononuclear, hexa-coordinated and octahedral structure with six dimethylpropyleneureas.
