The general structure of an ether. R and R' represent most organyl substituents.. In organic chemistry, ethers are a class of compounds that contain an ether group—a single oxygen atom bonded to two separate carbon atoms, each part of an organyl group (e.g., alkyl or aryl).
In chemistry, a transition metal ether complex is a coordination complex consisting of a transition metal bonded to one or more ether ligand. The inventory of complexes is extensive. [2] Common ether ligands are diethyl ether and tetrahydrofuran. Common chelating ether ligands include the glymes, dimethoxyethane (dme) and diglyme, and the crown ...
Crown ethers have been shown to coordinate to Lewis acids through electrostatic, σ-hole (see halogen bond) interactions, between the Lewis basic oxygen atoms of the crown ether and the electrophilic Lewis acid center. [3] [4] Structures of common crown ethers: 12-crown-4, 15-crown-5, 18-crown-6, dibenzo-18-crown-6, and an aza-crown ether
In chemistry, a template reaction is any of a class of ligand-based reactions that occur between two or more adjacent coordination sites on a metal center. In the absence of the metal ion, the same organic reactants produce different products. The term is mainly used in coordination chemistry.
Ether cleavage refers to chemical substitution reactions that lead to the cleavage of ethers. Due to the high chemical stability of ethers, the cleavage of the C-O bond is uncommon in the absence of specialized reagents or under extreme conditions. [1] [2] In organic chemistry, ether cleavage is an acid catalyzed nucleophilic substitution reaction.
The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol . This reaction was developed by Alexander Williamson in 1850. [ 2 ] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction .
Inhaled agents like diethyl ether are critical in anesthesia. Diethyl ether initially replaced non-flammable (but more toxic) halogenated hydrocarbons like chloroform and trichloroethylene. Halothane is a halogenated hydrocarbon anesthetic agent that was introduced into clinical practice in 1956. Due to its ease of use and improved safety ...
Ether on sn-2 and sn-3: this class with flipped chirality on the phosphate connection is called an "archaeal ether lipid". With few (if any) exceptions, it is only found among archaea . The part excluding the phoshphate group is known as archaeol .
