通过乙酰丙酮与乙二胺、1,4-丁二胺或1,6-己二胺的反应分别制备了14-、18-和22-元四氮杂大环。他们的铜(II)和镍(II)配合物通过电子和红外光谱表征。14元大环形成具有平面结构的单核铜(II)配合物,而18元大环形成具有伪四面体结构的单核铜(II)配合物,22元大环形成双核和三核铜 (II) 络合物。讨论了这些大环化合物对铜 (II) 和镍 (II) 离子的络合和萃取能力。
18- and 22-membered tetraaza macrocycles were prepared from acetylacetone and 1,4-diaminobutane or 1,6-diaminohexane, respectively. Their copper(II) complexes were characterized by electronic spectroscopy and the copper(II) complex of the 18-membered macrocycle was found to be pseudo-tetrahedral.
