摘要 在无水无氧的条件下,利用2-(二甲胺基)苄基钾盐KR或锂盐LiR(R=CH_2C_6H_4-NMe_2-o与三氯化稀土反应制得相应的均配型的三[2-(二甲胺基)苄基]稀土配合物LnRa(Ln=La,Nd,Y).配合物LnR_3能够有效地催化Henry反应,反应条件温和,产率中等. A series of homoleptic tris（o-dimethylaminobenzyl） complexes LnR3 （R= CH2C6H4-NMe2-0; Ln=La, Nd, Y） were prepared through a reaction of anhydrous LnC13 and KR/LiR under pure argon by rigorously excluding air and moisture and using standard Schlenk techniques. Tris（o-dimethylaminobenzyl） lan- thanide complexes could catalyze the Henry reaction efficiently under mild conditions, with moderate to high yields.
