He is best known today for the Williamson ether synthesis.

This method is a variant of the Williamson ether synthesis.

Williamson ether synthesis, one of the most common methods for preparing ethers.

Addition of cyclopentyl to isovanillin via Williamson ether synthesis.

With alkyl halides alkoxides give rise to ethers in the Williamson ether synthesis.

Williamson ether synthesis.

The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and an alcohol.

Its steric bulk inhibits the group from participating in nucleophilic addition, such as in a Williamson ether synthesis or an S2 reaction.

For example, inorganic reagents (such as potassium carbonate in a Williamson ether synthesis) are ignored as they are not incorporated into the final product.

Important carbon-oxygen bond forming reactions are the Williamson ether synthesis, nucleophilic acyl substitutions and electrophilic addition to alkenes.

Williamson is credited for his research on the formation of ether by the interaction of sulphuric acid and alcohol, known as the Williamson ether synthesis.

Anisole is prepared by the Williamson ether synthesis, reacting sodium phenoxide with methyl bromide and related methylating reagents:

Alkoxides, although generally not stable in protic solvents such as water, occur widely as intermediates in various reactions, including the Williamson ether synthesis.

Reaction with alkoxides or aroxides give ethers in the Williamson ether synthesis; reaction with thiols give thioethers.

Elemicin was later synthesized from syringol and allyl bromide using Williamson ether synthesis and Claisen rearrangement.

This ether may also be prepared by way of the Williamson ether synthesis in which n-propoxide, the conjugate base of n-propanol, is reacted with an n-propyl halide:

This compound is prepared by a modified Williamson ether synthesis in the presence of a templating cation: It can be also prepared by the oligomerization of ethylene oxide:

One is a typical Williamson ether synthesis using an MTM halide as an MTM resource and sodium hydride (NaH) as a base.

It is synthesized by a modification of the Williamson ether synthesis, here the reaction of phenol and bromobenzene in the presence of base and a catalytic amount of copper:

Phenacetin may be synthesized as an example of the Williamson ether synthesis: ethyl iodide, paracetamol, and anhydrous potassium carbonate are refluxed in 2-butanone to give the crude product, which is recrystallized from water.

Another reaction that can be used for the preparation of ethers is the Williamson ether synthesis, in which an alkoxide (produced by dissolving an alkali metal in the alcohol to be used) performs a nucleophilic substitution upon an alkyl halide.
