procedures for monoazathiacrown ethers were explored, and monoazatrithia-12-crown-4, monoazatetrathia-15-crown-5, and monoazapentathia-18-crown-6 were obtained in moderate yields by the reaction of bis(2-chloroethyl)amine with the appropriate dithiols in the presence of lithium hydroxide in THF. To evaluate metal-ion binding properties of the monoazathiacrown ethers by solvent extraction, lipophilic dodecyl
探索了单氮杂蒽酮醚的合成方法,并通过双(2-氯乙基)胺与双(2-氯乙基)胺的反应以中等收率获得了单氮杂trithia-12-crown-4,单氮杂异硫磷-15-crown-5和单氮杂戊硫杂-18-18-crown-6。在氢氧化锂存在下,在THF中加入合适的二硫醇。为了评估通过溶剂萃取的单氮杂冠氮醚的金属离子结合性能,将亲脂性十二烷基和十二烷酰基结合到单氮杂冠氮醚上。溶剂萃取实验表明,单氮杂冠冕醚具有Ag(+)和Hg(2+)选择性,并且Ag(+)和Hg(2+)之间的相对选择性取决于它们的氮原子特性和反映各自的硫原子数氮和硫原子对Hg(2+)和Ag(+)的亲和力
