Procedure

By reacting 1.38 mmole of 1,4-diphenyl 1,3-butadiene with 5.52 m atoms of cerium as powder in 8 ml of DME, with temporary application of ultrasound, a solution of 1,4-diphenyl 1,3-butadiene cerium has been obtained. AFter action of a methanol excess and the usual treatment, 1,4-diphenylbutenes (three isomers) were isolated with a yield of 295.
