2-Acryloyloxymethyl crown ether, Aza-crown ether, Bis-crown ether, Tris-crown ether
Novel bis- and tris-crown ethers were synthesized from 1-aza and diaza-crown ethers with 2-acryloyloxymethyl crown ethers through Michael addition. The synthesized bis- and tris-crown ethers were characterized by their elemental analyses, 1H-NMR, 13C-NMR, mass spectra, IR spectra, respectively. The complexation behavior of the bis- and tris-crown ethers with Li+, Na+, K+, Rb+, Cs+ was examined by 1H-NMR, FAB mass, and UV spectrometry.
