Ethyl vinyl ether synthesis.

It displayed advantageous properties for the construction of oligonucleotides since it could be cleaved with 5 acetic acid without affecting the internucleotide bond. As a similar protecting function the 1 ethoxyethyl ether formed by reaction of the alcohol with ethyl vinyl ether was introduced scheme 28. 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. Ethyl vinyl ether is made by reaction of acetylene and ethanol in presence of a base.

The alkene portion of the molecule is reactive in many ways. Ethyl vinyl ether stabilized with koh 純度 試験方法. Polymerization is typically initiated with lewis acids such as boron trifluoride.

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. It is prone to polymerization leading to formation of polyvinyl ethers. 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.
