苯并-15-冠-5与轻稀土配合物的研究早有报道。标题化合物,氮杂苯并-15-冠-5(L)稀土配合物尚未见报道。由于NH取代了冠醚环上的一个氧,使冠醚本身具有一定的碱性,致使其稀土配合物合成比较困难。本文采用不同脱水剂合成了氮杂苯并-15-冠-5与硝酸镧(镨、钕)的配合物,并对其进行了表征。
Benzo-15-crown-5 and light rare earth complexes have long been reported. The title compound, aza-benzo-15-crown-5 (L) rare earth complexes have not been reported. Because NH replaces an oxygen on the crown ether ring, the crown ether itself has some alkalinity, which makes the synthesis of rare earth complexes more difficult. In this paper, the complexes of aza-15-crown-5 with lanthanum nitrate (praseodymium and neodymium) were synthesized and characterized by different dehydrating agents.
