용도

Ethyl vinyl ether is used in fragrances, lubricating oil additives and spices preparation. It acts as an intermediate for sulfadiazine. It finds application in pharmaceuticals as anesthetics and analgesics. Further, it is used as a solvent in organic synthesis.

참고

Air sensitive. Incompatible with strong oxidizing agents, oxygen and acids. Store in a cool place.

Acid-catalyzed reaction with alcohols gives 1-ethoxyethyl (EE) ethers, useful as protected derivatives, e.g. in reactions with organometallics. Possible catalysts include: tosic acid: J. Am. Chem. Soc., 101, 7104 (1979); Org. Synth., 76, 199 (1998), PPTS: Tetrahedron Lett., 28, 4303 (1987), or dichloroacetic acid: J. Org. Chem., 37, 1947 (1972). Cleavage of this mixed acetal occurs in dilute acid, more readily than THP ether (see 3,4-Dihydro-2H-pyran, L02731). Protection of cyanohydrins allows use as acyl anion equivalents: Org. Synth. Coll., 7, 381 (1990):

Also used in the protection of phenols as EE ethers which can be cleaved by acid-catalyzed methanolysis: J. Am. Chem. Soc., 119, 8071 (1997).

In the presence of Montmorillonite K10, an addition reaction with diethyl acetals gives the ß-ethoxy acetal of the bis-homologated aldehyde, providing, on acid cleavage, an effective route to the corresponding ɑß-unsaturated aldehyde: Synthesis, 137 (1981).
