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.
Molecular design of the electron-donating sidearm of lariat ethers: effective coordination of the quinoline moiety in complexation toward alkali-metal cations
