Various zirconacyclopentadienes fully substituted at the metallacycle react with ethynylferrocene in the presence of [NiBr2(PPh3)2] or with methyl or ethyl 3-ferrocenylpropynoates in the presence of CuCl to give penta- and hexasubstituted phenylferrocenes, respectively. X-Ray diffraction analysis showed that the cyclopentadienyl and benzene rings in (5,8-diphenyl-1,2,3,4-tetrahydronapthalen-6-yl)ferrocene are rotated by as much as 51°.
