Popis:	Soluble oligo-(1,1'-ferrocenylene-2,5-dihexylphenylene) and oligo-(1,1'-ferrocenylene-2,5-didodecyloxylphenylene) were prepared by the Suzuki coupling of the ferrocene diboronic acid and the 1,4-phenylene diiodide. Directreaction of lithium 1,4-bis(tetramethylcyclopentadienide)benzene or lithium 2,5-bis(tetramethylcyclopentadienide)thiophene with Fe(II) halides afforded insoluble ferrocenylenearylene oligomers, and with W(CO) 6 followed by Mel gave a model dimer whose crystal structure was determined. The magnetic properties of the ferrocene oligomers exhibit anomalous behavior that is explained in terms of the properties of the individual ferrocene groups, rather than to cooperative behavior.
