Phenylferrocenylacetylene was found to be capable of oligomerizing in the presence of WCl<sub>6sub> (130聽掳C, 24聽h) to afford short polyenes (with about 5 monomer units in the macromolecule) in up to 鈭?0%yield. The polyenes synthesized are promising reactive macromonomers and building blocks for high-tech materials.
