Ethyl vinyl ether synthesis.

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

The alkene portion of the molecule is reactive in many ways. Download high res image 70kb. Sigma aldrich offers a number of ethyl vinyl ether products.
