摘要: 含中心功能基的冠醚化合物及其对金属离子的络合行为,已有较多的报导[1-5]。Cram[1.2]等报导,在含芳环的冠醚中,苯环的1,3位有二个亚甲基单元占据时,处于2位上的甲氧基、羟基、硝基、卤素等带孤对电子的中心功能基,可以用来调节冠醚环的空腔大小,致使其对金属离子的络合选择性有所改变。由于氧杂冠醚对碱金属和碱土金属离子具有较好的络合作用,而对过渡金属和重金属离子等的络合行为则不甚满意。因此,以氮、硫等杂原子代替冠醚环中的氧原子时,会对过渡金属和重金属离子产生明显的络合效果[6]

Abstract: This paper reports synthesis of 8 new azacrown ether compounds.Condensation of 2,6-bis(bromomethyl)-4-methyl (or 4-chloro)-anisole with N-substitutcd diethanolamines gave azacrown ether compounds (Ⅰ-Ⅷ) containing central functional group.All these compounds were identified by elemental analysis,IRand >sup>1H NMR.Compound(Ⅰ,Ⅱ,Ⅵ)were determined by MS.These results shown that the cyclic products were condensed with 2:2 molecular ratio.This work explored the methods for the purification of these new compounds.
