Method for producing alkenyl ethers
-
, (2008/06/13)
Alkenyl ethers are prepared by reacting the corresponding alcohols or phenols with acetylenes in the liquid phase in the presence of basic alkali metal compounds and a cocatalyst comprising compounds of the formula (Ia) and/or (Ib) R1O—(CH2CH2CH2CH2O)n—H??(Ia) R1O—(CH2CH2CH2CH2O)n—H2,??(Ia) where R1, R2 are, independently of one another, C1-C6-alkyl or C2-C6-alkenyl, or R1 and R2 together form a butyl unit and n is 1, 2, 3, 4 or 5.
17O NMR Spectra of Vinyl Ethers

, p. 353 - 357 (2007/10/02)
The 17O spectra of 58 α,β-unsaturated (vinyl) ethers were recorded in CDCl3 solution.The dependence of the chemical shift on the number and position of alkyl substituents in the vinyl moiety and on the nature and bulkiness of the alkoxy group was explored.The oxygen chemical shifts proved to be sufficiently sensitive to structural factors to make 17O NMR spectroscopy a useful tool in the investigation of the electronic and spatial syructures of vinyl ethers. - Keywords: NMR 17O NMR Vinyl ethers
