Abstract

Abstract A new catalytic system CsF-NaOH was developed for the synthesis of mono-and divinyl ethers of alkanediols exceeding in efficiency KOH. The nucleophilic addition of diols to acetylene in the presence of this system occurs both at enhance pressure (without solvent, 140–160° C) and atmospheric pressure (in DMSO medium, 100° C) of acetylene. Conditions were established of a selective preparation in a high yield of divinyl ethers ...
