Which is the most common method of ether synthesis?
The Williamson ether synthesis is the most widely used method to produce ethers. It occurs by an SN2 reaction in which a metal alkoxide displaces a halide ion from an alkyl halide. The alkoxide ion is prepared by the reaction of an alcohol with a strong base such as sodium hydride.
What is the mechanism of the Williamson ether synthesis?
What is Williamson Synthesis? The Williamson ether synthesis is an organic reaction in which an organohalide and deprotonated alcohol (alkoxide) are mixed to create an ether. Alexander Williamson invented this reaction in 1850. It normally involves an SN2 reaction between an alkoxide ion and a primary alkyl halide.
How does Williamson ether react with an alkoxide?
Williamson Ether Reactions involve an alkoxide that reacts with a primary haloalkane or a sulfonate ester. Alkoxides consist of the conjugate base of an alcohol and are comprised of an R group bonded to an oxygen atom. They are often written as RO –, where R is the organic substituent.
Which is a good candidate for Williamson synthesis?
Besides the alkyl halides, tosylates and mesylates are other excellent candidates for reacting with alkoxides in Williamson synthesis: Williamson Synthesis for Symmetrical and Unsymmetrical Ethers Williamson synthesis can be used to prepare symmetrical and unsymmetrical ethers:
