一茂二元羧酸钕的合成

Synthesis of Clicyclopentadienyl Neodymium Dicarboxylates

用三茂钕和二元羧酸反应,合成了五个新的含有茂基的有机钕配位物:(COO)_2NdC_5H_5·THF(1), CH_2(COO)_2NdC_5H_5·THF(2), (CHCOO)_2NdC_5H_5·THF(3), (CH_2COO)_2NdC_5H_5·THF(4), O-C_6H_4(COO)_2NdC_5H_5·THF(5)。由于这些配位物具有螯合环的结构,在空气中的稳定性比较高。这些配位物均经元素分析和红外光谱鉴定。

By the reaction of Cp,Nd ( Cp=C_5H_5) with dicarboxylic acid, five new cyclopentadienyl neodymium dicarboxylates have been synthesized. Namely: (COO)_2NdC_5H_5·THF(1), CH_2 (COO)_2NdC_5H_5·THF(2), (CHCOO)_2NdC_5H_5·THF(3), (CH_2COO)_2 NdC_5H_5·THF(4), O-C_6H_4(COO)_, NdC_5H_5·THF(5). They are stable by exposure to air. It may be attributed to the effect of chelate ligand. They were identified by elemental analysis and IR.
