WebYou can also use the Williamson synthesis to produce cyclic ethers. You need a molecule that has a hydroxyl group on one carbon and a halogen atom attached to another carbon. This molecule will then undergo an S N 2 reaction with itself, creating a cyclic ether and a halogen anion. Is epoxide cyclic ether? An epoxide is a cyclic ether with a ... Webesters, and cyclic ethers of various ring-sizes, is of upmost synthetic importance. Recent papers have indeed shown that the mechanism of ester hydrogenation by complex hydrides or silanes can be controlled by Lewis acids and some organometallic species, and preferred formation of ethers has been achieved.
