Ether synthesis by etherification (alkylation) - Organic Chemistry …
An iridium-catalyzed 1,3-rearrangement of readily available allylic ethers provides allylic ethers with a large steric hindrance. The developed method shows a broad substrate scope and could be used in the late-stage modification of several natural products.
Etherification - an overview | ScienceDirect Topics
Etherification is a straightforward approach that can be used to functionalize pillar[n]arenes from perhydroxylated pillar[n]arenes. Various functionalized pillar[5]arene derivatives are accessible by etherification of perhydroxylated pillar[n]arenes with alkyl halides or alkyl tosylates in the presence of appropriate bases. Pillar[5]- and ...
Etherification - an overview | ScienceDirect Topics
Etherification can be divided into four types based on the type of products obtained from the etherification process: (1) nonionic etherification, (2) cationic etherification, (3) anionic etherification, and (4) amphoteric etherification.
Williamson Ether Synthesis - Chemistry LibreTexts
2023年1月23日 · The Williamson Ether synthesis is the easiest, and perhaps the fastest, way to create ethers. 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.
Etherification - an overview | ScienceDirect Topics
Etherification is one of the most modification techniques reported in the literature. To carry out the process, cellulose fibers are carboxymethylated.
Aryl ether synthesis by etherification (alkylation)
The allylic amination and etherification of a broad range of allylic carbonates occurred in high yields and with high regioselectivities and enantioselectivities with an activated metallacyclic iridium catalyst containing a bis-naphthethylamino group.

3. Reductive Etherification of Alcohols with Carboxylic Acid …
In this Review, an update of the recent progresses in the area of catalytic reductive alcohol etherifications using carbonyl‐based compounds and CO 2 have been described with a special focus on organic synthetic applications and catalyst design.
Iron-Catalyzed Selective Etherification and Transetherification ...
2018年1月1日 · Simple and readily available iron (III) triflate turned out to be a cheap, environmentally benign, and efficient catalyst for the direct etherification of alcohols.
Ether synthesis by reductive etherification - Organic Chemistry …
A simple iron- and silyl chloride catalyzed reductive etherification enables the preparation of symmetrical and nonsymmetrical ethers from various aldehydes and ketones in the presence of triethylsilane as a reducing agent and catalytic amounts of iron(III) oxo acetate and chloro(trimethyl)silane.
