Etoch ch 2 roh etoch or ch 3 this alcohol protection reaction is akin to the behavior of dihydropyran. The first two reactions proceed by a sequence of s n 2 steps in which the iodide or bromide anion displaces an alcohol in the first step and then converts the conjugate acid of that alcohol to an alkyl halide in the second. Reaction vinyl ether hydroxy vinyl ethers prior art date 1950 03 02 legal status the legal status is an assumption and is not a legal conclusion.

Ethyl vinyl ether and n butyl vinyl ether may be distilled from k 2 co 3 or na if purification of the commercial materials is desirable. Google has not performed a legal analysis and makes no representation as to the. The reaction mixture was stirred at reflux under n 2 for 24 h then the excess ethyl vinyl ether was removed under vacuum. The conjugate acid of the ether is an intermediate in all these reactions just as conjugate acids were intermediates in certain alcohol reactions.

With catalytic amounts of acids ethyl vinyl ether adds to alcohols to give the mixed acetal. All three compounds react violently with halogens and with strong oxidizing agents and undergo rapid polymerization in the presence of acids. 35 5 deg is accompanied by diethyl ether b p.
