The activity of well-known alkaline-containing catalyst systems for the formation of vinyl ethers from alcohols and acetylenes can be remarkably increased by using a superbasic system: KOR-crown ether in an aprotic solvent (especially in hydrocarbons).To achieve a high catalytic activity a low concentration of alcohol in the hydrocarbon phase is essential.The results are discussed in terms of solvatation of alcoholate anion.
