Procedure

The powdery catalyst that had been prepared in the same manner as in Example 1 was incorporated with 1000 g of toluene that had been dehydrated with molecular sieve, in a stream of nitrogen with heating to 110° C. Subsequently 70 g of 1,3-butadiene was introduced into the reaction system with vigorous stirring for one (1) hour to carry out the reaction. After cooling the system, the catalyst was deactivated by adding isopropyl alcohol thereto and then the reaction liquid was sampled for analysis by gas chromatography- As a result, the objective phenyl-2-pentene was obtained in a yield of 77.2%.
