Fluorination of enolizable ketones gives a mixture of the difluoroalkane and vinyl fluoride. In glyme with fuming sulfuric acid , the vinyl fluoride product predominates. [ 11 ] Electron-rich carbonyl compounds, such as esters and amides, do not react with DAST or other aminosulfuranes.
Dimethoxyethane is also a good solvent for oligo- and polysaccharides. Sodium naphthalide dissolved in dimethoxyethane is used as a PTFE etching solution that removes fluorine atoms from the surface, which get replaced by oxygen, hydrogen, and water. This physically etches the surface as well to prepare the surface for better adhesion.
Glyme may refer to: Any of the glycol ethers, a class of solvents, usually dimethoxyethane if not otherwise specified; River Glyme, a river in Oxfordshire, England
As alkenes can polymerize in somewhat straightforward radical reactions, they form useful compounds such as polyethylene and polyvinyl chloride (PVC), [3] which are produced in high tonnages each year [3] due to their usefulness in manufacturing processes of commercial products, such as piping, insulation and packaging.
Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical, and whether the substrate is aliphatic or aromatic. Detailed understanding of a reaction type helps to ...
The heteroatom stabilizes the formation of a free radical which is formed by the abstraction of a hydrogen atom by another free radical. [clarification needed] The carbon-centered free radical thus formed is able to react with an oxygen molecule to form a peroxide compound. The process of peroxide formation is greatly accelerated by exposure to ...
The simplest alkene, ethylene (C 2 H 4) (or "ethene" in the IUPAC nomenclature) is the organic compound produced on the largest scale industrially. [ 5 ] Aromatic compounds are often drawn as cyclic alkenes, however their structure and properties are sufficiently distinct that they are not classified as alkenes or olefins. [ 3 ]
Within the field of geology, Bowen's reaction series is the work of the Canadian petrologist Norman L. Bowen, [1] who summarized, based on experiments and observations of natural rocks, the sequence of crystallization of common silicate minerals from typical basaltic magma undergoing fractional crystallization (i.e. crystallization wherein early-formed crystals are removed from the magma by ...
