Ethyl vinyl ether synthesis.

Ethyl vinyl ether stabilized with koh 純度 試験方法. The alkene portion of the molecule is reactive in many ways. As a similar protecting function the 1 ethoxyethyl ether formed by reaction of the alcohol with ethyl vinyl ether was introduced scheme 28. Download high res image 70kb.

Allyl vinyl ethers are typically prepared by either mercury or acid catalyzed vinyl ether exchange with allylic alcohols or acid catalyzed vinylation of allylic alcohols with acetals 29 however yields in these reactions are often low and the use of mercury is not without concerns. Advanced search structure search cert of analysis. Ethyl vinyl ether is made by reaction of acetylene and ethanol in presence of a base. It displayed advantageous properties for the construction of oligonucleotides since it could be cleaved with 5 acetic acid without affecting the internucleotide bond.

While vinyl ethyl ether can be produced by either 1 2 h or 1 2 ethoxy shift in the carbine both theoretical calculations and deuterium labeling experiments supported the 1 2 h route. Sigma aldrich offers a number of ethyl vinyl ether products. It is prone to polymerization leading to formation of polyvinyl ethers. Ethyl vinyl ether stabilised with potassium hydroxide for synthesis synonym.

Polymerization is typically initiated with lewis acids such as boron trifluoride. Li synthesis 2008 3487 3488. An efficient method chemoselectively converts benzyl alcohols into their methyl or ethyl ethers in the presence of aliphatic or phenolic hydroxyl groups using 2 4 6 trichloro 1 3 5 triazine tct and dimethyl sulfoxide in methanol or ethanol.
