Unlike most ethers, oxacyclopropanes react readily with nucleophilic reagents. These reactions are no different from the nucleophilic displacements previously encountered in Chapter 8, except that the …
WebAside from their synthesis, ethers only react under specific circumstances. For example, epoxides are a type of ether in which the oxygen and the carbon atoms directly attached to it form a three-membered ring. Because the bond angles are small, the ring is strained and can be broken in either acidic or basic conditions. Williamson Ether Synthesis
