A “crown ether ” is a cyclic ether containing several (i.e., 4, 5, 6 or more) oxygen atoms. It is possible to dissolve ionic compounds in organic solvents using crown ethers. Cyclic polyether …

Crown ethers, discovered in the early 1960s by Charles Pedersen at the DuPont Company, are a relatively recent addition to the ether family. They are named according to the general format x …

Crown ethers are cyclic compounds made up of multiple oligo-ethylene oxides arranged in a cyclic structure. They are known for their strong binding ability with metal ions and electron-rich …

Jan 24, 2023 · What are Crown Ethers? The cyclic polyether containing four or more ether linkages in a ring of \ (12\) or more atoms are called crown ethers. Crown ethers were given …
