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 from diols. 2005 Pleiades Publishing, Inc.

Acetylene adds to butane-1,3-diol in the presence of KOH to give, along with the corresponding divinyl ether and 2,4-dimethyl-1,3-dioxane, 4-vinyloxybutan-2-ol and its structural isomer 3-vinyloxybutan-1-ol, the ratio between the latter two products, (5 - 8) : 1, depending on the reaction conditions.
