以苯并杂环为端基的非环多醚化合物的合成

Synthesis of Noncyclic Polyethers with Benzoheterocycle as End Groups

由于非环多醚化合物分子可以根据其不同的化学结构而呈现不同的柔曲性,因而可能选择性地络合具有不同离子半径的金属离子。而其柔曲程度则完全依赖于端基、氧乙烯单元数目及端基与氧乙烯链的结合方式。已证明甲巯咪唑为端基的非环多醚对Au3+、UO22+离子的配位能力极强,但对苯并唑类杂环为端基的非环多醚的研究未见报道。由于唑类化合物对过渡金属离子有较强的配位能力,因此我们选择2（3H）—苯并噁唑酮和苯并三唑为端基。

Eight noncyclic polyethers with 2(3H)-benzoxazolone or benzotriazole as end groups were synthesized. Their compositions and structures were identified by elemental analysis, IR, MS or 1H NMR spectra. The priliminary experiment reveals their excellent coordination property with uranyl ions.
