Vinüüleeterrühm

Vinüüleeterrühm, also known as a vinyl ether group, is a functional group characterized by an oxygen atom directly bonded to a vinyl group (a carbon-carbon double bond) and an alkyl or aryl group. Its general formula can be represented as R-O-CH=CH2, where R is the alkyl or aryl substituent. The presence of the double bond makes vinyl ethers reactive in addition reactions, particularly polymerization.

These compounds are typically formed through the addition of an alcohol to acetylene under basic conditions, a reaction known as the vinylation of alcohols. Alternatively, they can be synthesized via the dehydrohalogenation of haloethers. Vinyl ethers are known for their susceptibility to electrophilic attack at the carbon atom of the double bond that is more substituted. This reactivity makes them useful intermediates in organic synthesis.

Industrially, vinyl ethers find application as monomers in the production of polymers and copolymers. These polymers often exhibit unique properties such as good adhesion, flexibility, and resistance to water and chemicals. They are used in various products including adhesives, coatings, and textile finishes. The specific properties of the resulting polymer depend on the nature of the R group attached to the ether oxygen and the polymerization conditions.
