| abstract | a) durch Umsetzung eines Phosphoniumsalzes der Formel IIa n n R¹-CH₂-P⁺(C₆H₅)₃ X⁻ IIa n nin der X für Chlor, Brom und Jod steht, mit einem Aldehyd nder Formel IIIa oder seinem Halbacetal der Formel nIIIb n noder b) durch Umsetzung eines Phosphoniumsalzes der Formel IIb n n (C₆H₅)₃P⁺(CH₂) n+1 OH X⁻ IIb n nmit einem Aldehyd der Formel IV n n R¹CHO IV n nin einem Lösungsmittel in Gegenwart einer Base, dadurch ngekennzeichnet, daß man als Base das Alkalimetallsalz neines Alkohols und als Lösungsmittel einen Alkohol verwendet. Process for the preparation of alkenols of formula I. R¹-CH = CH (CH₂) n OH I in which R¹ is hydrogen or a hydrocarbon radical and the index n is an integer from 3 to 15, a) by reacting a phosphonium salt of the formula IIa R¹-CH₂-P⁺ (C₆H₅) ₃ X⁻ IIa in which X represents chlorine, bromine and iodine, with an aldehyde of the formula IIIa or its hemiacetal of the formula IIIb or b) by reacting a phosphonium salt of the formula IIb (C₆H₅) ₃P⁺ (CH₂) n + 1 OH X⁻ IIb with an aldehyde of formula IV R¹CHO IV in a solvent in the presence of a base, characterized in that the alkali metal salt of an alcohol is used as the base and an alcohol is used as the solvent. |
