Reaction Steps

1,8-Bis(p-bromophenyl)-1,7-octadiyne (0.191 g, 0.459 mmol) was added at −78° C. to a THF solution of bis(η5-cyclopentadienyl)dibutylzirconium in THF, which was prepared from bis(η5-cyclopentadienyl)dichlorozirconium (0.161 g, 0.551 mmol) and n-butyl lithium (0.7 ml, 1.6 M, 1.1 mol/l). The mixture was then allowed to stand at room temperature for an hour. CuCl (0.095 g, 0.964 mmol), DMPU (0.17 ml, 1.38 mmol) and 2,3-diiodo-9,10-dipropylanthracene (0.236 g, 0.459 mmol) were added to the mixture. After heating at 50° C. for an hour, the solvent in the mixture was removed in vacuum. Column chromatography (chloroform) was performed. By recrystallization in chloroform/methanol, the title compound (0.177 g) was obtained as orange red. The isolation yield was 57%.
