ABSTRACT:
A process is described for the preparation of 2-alkenyl 1,1,2-trifluoro-2-halogenoethyl ethers by reacting optionally substituted allyl alcohols with fluoroolefins in the presence of an alkali metal hydroxide as catalyst, in which the reaction is carried out by intimately mixing the reactants with an N,N-dialkylcarboxylic acid amide. The said ethers are suitable as intermediate products for the preparation of addition products by the addition of alcohols, primary or secondary amines or R.sub.3 SiH compounds, and are also suitable as comonomers for fluorine-containing copolymers.
