Organomagnesium Crown Ethers and Their Binding …

In organic chemistry, crown ethers are cyclic chemical compounds that consist of a ring containing several ether groups (R−O−R’). The most common crown ethers are cyclic oligomers of ethylene oxide, the repeating unit being ethyleneoxy, i.e., −CH2CH2O−. Important members of this series are the tetramer (n = 4), the pentamer (n = 5), and the hexamer (n = 6). The term "crown" refers to the res… Webether [e´ther] 1. an organic compound containing an oxygen atom bonded to two carbon atoms. 2. diethyl or ethyl ether: a colorless, transparent, mobile, very volatile, highly … Web3.02.3.6 Anion Binding.
