Firstly,two novel rare earth complexes(CH_2=CHO)Ln~Ⅲ[2,6-_2PhNSiMe _3]_2Li_3Ln=Y(2,Yb(3)containing arylamido and enolate mixed ligands have been synthesized by treatment of 2 equiv of of 2,6-~iPr_2PhNHSiMe_3 with exces n-BuLi at -78℃in THF for 12h,followed by reaction with 1 equiv of LnCl_3at 80℃for 24h in one-pot.All the two compounds were characterized by spectroscopic methods,elemental analyses,and a single-crystal X-ray diffraction study.

首先，-78℃下，在两当量的2，6-~iPr_2PhNHSiMe_3(1)THF溶液中加入过量的n-BuLi，反应12小时，再加入一当量的LnCl_380℃下，反应24小时，一锅法合成了含胺基、乙烯醇基混合配体的新型稀土金属配合物(CH_2=CHO)Ln~Ⅲ[2，6-_2PhNSiMe_3]_2Li_3Ln=Y(2、Yb(3)，上述化合物结构经单晶X-ray衍射、光谱和元素分析表征，表明我们得到的是一类新型的三价稀土配合物。

They readly enolize in alkaline soluions to reduce ions such as cu2+ and fe63-. therefore, they are called "reducing sugars".

它们在碱性溶液中易于烯醇化而使cu2+、fe63+之类的离子还原，因此称它们为&还原糖&。
