실험 절차

Proceeding as in Example 1, into a 100 cc flask were placed to react: 4.1 g of potassium 3-butenoate (3.3 10-2 mols), 6 g of styryl bromide, a cis-trans mixture, (3.3 10-2 mols), 2.9 g of Ni(PPh3)3 (3.3 10-2 mols) and 40 cc of ethyl alcohol. The mass was heated up to 105° C. under nitrogen atmosphere, for about 2 hours. Operating as in Example 1, there were obtained 2.2 g of 6-phenyl-3,5-hexadienoic acid, a mixture of isomers containing double cis and trans bonds.
