Several 16-crown-5 derivatives having an electron-donating sidearm were newly prepared and their stability constants toward Na+ and K+ were measured. The difference in the position of the sidearm was disclosed to change remarkably the complexation property of such type of compounds.
新制备了数种具有电子供体侧臂的
16-冠-5衍
生物,并测定了它们对Na+和K+的稳定常数。发现侧臂位置的差异显著改变了此类化合物的配位性质。
