Versuchsvorschrift

After the flask was heated at a temperature of 110° C. during stirring in order to disperse the catalysts, 1,3-butadiene was fed for 6 hours at a flow rate of 0.3 mol/hour in order to promote the addition reaction. After the completion of the reaction, water was added to deactivate and separate the catalysts. The thus obtained reaction mixture was analyzed by gas chromatography. The results indicated that 5-(3-methoxyphenyl)-2-pentene was produced at 79% yield with respect to the consumed m-methoxytoluene.
