Development of a highly efficient catalytic method for synthesis of vinyl ethers
A new method for the preparation of alkyl vinyl ethers has been developed. Thus, various types of alkyl vinyl ethers were synthesized by the reaction of alcohols with vinyl acetate under the influence of a catalytic amount of [Ir(cod)Cl]2 combined with Na2CO3 in good to excellent yields. Copyright

Purification of alkenyl compounds
A process for purifying alkenyl compounds having a divalent or trivalent heteroatom in the à-position relative to the double bond by distillation comprises carrying out at least two distillations in which the purified alkenyl compounds are obtained from the gas phase by condensation, where the time between the first distillation after the synthesis of the alkenyl compounds and at least one further distillation is at least one day and the purified alkenyl compounds have an APHA color number of 30.

Nucleophilic addition to acetylenes in superbasic catalytic systems. IX. Anions of oligo(ethylene glycol)s and monomethyl ethers thereof
In superbasic system KOH-DMSO increases velocity and selectivity of nucleophilic addition of oligo(ethylene glycol)s and their monometyl ethers to acetylene. Accumulation of ethylene oxide units in the molecule additionally activates it to vinylation process due to formation of crown-like structure which increases the basicity of the medium and nucleophilicity of the reacting anions.
