摘要： 通过4,5-二溴甲基苯并-15-冠-5与2-萘酚和2-巯基苯并噻唑反应分别合成了两种新的双臂式苯并-15-冠-5(2和3),进而采用溶剂萃取的方法研究了它们与一些阳离子的键合行为.结果表明,冠醚2对碱金属钾离子和重金属铊离子表现出较高的选择性萃取能力,而冠醚3对重金属银离子表现出较高的选择性萃取能力.

Abstract: Two new double-armed benzo-15-crown-5(2 and 3) were synthesized by reaction of 4,5-bis-(bromomethyl)-benzo-15-crown-5 with 2-naphthol and 2-mercaptobenzothiazole, respectively, and characterized by elemental analysis, mass, IR, 1H NMR spectroscopies and X-ray diffraction, respectively. The crystal structure of compound 2 was reported as follows: Crown ether 2 crystallizes in the monoclinic system, space group P21 with cell parameters: a=1.262 2(9) nm, b=1.224 7(9) nm, c=2.016 0(16) nm, β=101.270(15)°. There is an intermolecular π*
