摘要
用1,4—二(2′—甲酰基苯基)—1,4-二氧杂丁烷和1,7—二(2′—甲酰基苯基)—1,4,7—三氧杂庚烷,在相转移催化剂存在下,用 KMnO_4氧化,制得了两种键端为羧酸的开链聚醚配体:2,2′—(1,4—亚乙二氧基)—二苯甲酸(H_2L^1)和2,2′—(1,7—二乙醚二氧基)—二苯甲酸(H_2L^2)。用元素分析,红外光谱对它们进行了表征。在甲醇或水介质中,制得了 H_2L^1和 H_2L^2的镧系元素固体配合物,通式分别为 LnL^1(NO_2)·nH_2O 和 Ln_2L(_3~2)·nH_2O(Ln=La—Lu,Pm 除外);在甲醇介质中还制得了它们的 UO(_2^(2+))和 Th^(4+)配合物,UO_2L^1·6H_2O,UO_2L^2·3H_2O,ThL(~1_2)·H_2O 和 ThL(~2_2)·5H_2O。
Two sorts of open-chain polyether with two earboxylic groups at the ends of the chain were obtained by oxidation of 1,4-bis(2′-formylphenyl)-1, 4-bioxabutane and 1,7-bis(2′-formylpheuyl)-l,4,7-trioxaheptane respectively with KMnO,in water and benzene in the presence of PTC(Phase Transform Catalyst).These two sorts of open-chain polyether are 2,2′-(l,4-ethyl- enedioxy)-dibenzoie acid(H_2L^1)and 2,2′-(ethyl etherdioxy)-dibenzoic acid (H_2L^2).They were characterized by elemental analysis and IR. In methanol or water,we have prepared lanthanide complexes of H_2L^1 and H,L^2,which have the general formula of LnL^1(NO_3)·nH_2O and Ln_2L_3~2·H_2O(n=2-6,Ln=La-Lu,Pm exlcuded)respeetiveIy,and also UO_2^(2+)and Th^(4+)complexes of the ligands which have the formula UO_2L^1· 6H_2O,UO_2L^2·H_2O,ThL_2~1·H_2O and ThL_2~2·H_2.
