Abstract

Abstract: The electron-donating sidearm of alkyl-substituted lariat ethers based on 15-crown- 5, 16-crown-5, and 18-crown-6 was modified to clarify the contribution to the complexation of the sidearm toward alkali-metal cations. A specific coordination property of the quinoline sidearm was shown by measuring the complexing ability in methanol at 25'C, the change of the chemical shift in the'H NMR spectrum, a characteristic absorption in the UV spectrum, ...
