| Abstract: | The palladium-catalyzed Negishi-type C-C-coupling of the nonaromatic systems 2-indenyl and cyclopentadienyl were investigated. The employed catalyst played a decisive role in product formation. Instead of Pd(PPh3)4, the more bulky Pd(dppf)Cl2·CH2Cl2 led to the desired system in distinguished yields. |
