摘要

a -b , d -e -unsaturated carboxylic acid derivatives of formula R-CH=CH-CH2-CH=CH-COOR1 where R is H, phenyl or an aliphatic or cycloaliphatic hydrocarbon radical having not more than 10 carbon atoms, non-substituted or substituted providing the substituent is not an electronegative substituent in a conjugated position with a double bond, and R1 is H, a linear or branched saturated aliphatic, cycloaliphatic or an arylaliphatic hydrocarbon radical having not more than 10 carbon atoms, are prepared by reacting an alcohol R-CH=CH-CH2OH with a hydroxylated solvent R1OH, acetylene and carbon monoxide in the presence of nickel carbonyl and hydrochloric acid. Examples describe the preparation of: methyl and isopropyl 2,5-hexadienoates; 2,5-heptadienoic acid and its methyl ester; and methyl 6-phenyl-2,5-hexadienoate,
