Notizen:
Polystyrene derivatives react with the lithioferrocenes Fe(η5-C5H4Li)(η5C5H5),Fe(η5-C5H5),Fe(η5-C5H4Li)2,Fe[η5-C5H3(CHMeNMe2)Li-1,2] [η5-C5H5], and with lithium ferrocenylphosphines, to yield ironcontaining materials. The Mössbauer spectra confirm the loading of unstrained ferrocene fragments, some oxidized, in all cases. The 13C CP MAS NMR spectra also show the loading but the resolution (structural information) is not as good as can be obtained on model solid samples. Palladium(II) derivatives of the amine- and phosphine-containg materials are active hydrogenation catalysts for olefins. Double-bond migration also occurs in the case of 1-hexene.
