| 摘 要： | 研究了Dy(OTf)3、DyCl3和稀土双膦酸酯配合物{ ［Dy(OTf)2L2(H2O)2］(OTf)(CH3CN)}［L=(iPrO)2P(O)CH2P(O)(iPrO)2］ 等对Mannich 反应的催化作用，发现以Dy(OTf)3为催化剂时,收率为54%，［Dy(OTf)2L2(H2O)2］(OTf)(CH3CN)的收率仅为8%，DyCl3收率达47%。研究了12种稀土金属氯化物对Mannich 反应的催化作用，其中,ErCl3催化剂的收率最高，达到61%。

| Abstract: | The catalytic behaviors of Dy (OTf)3, DyCl3 and rare earth diphosphonate complex {Dy(OTf)2L2(H2O)2](OTf)(CH3CN)}L=(iPrO)2P(O)CH2P(O)(iPrO)2] were studied for Maanich reactions. The results showed that the yield of 54% ,8% and 47% were obtained over Dy(OTf)3, Dy(OTf)2L2(H2O)2](OTf)(CH3CN) and DyCl3, respectively. Among the twelve rare earth chlorides involved, ErCl3 attained the maximum yield 0f 61% for Mannich reactions. |
