In this work are described the syntheses of p-sexiphenyl and p-octiphenyl starting from 4-bromo-p-terphenyl and 4-bromo-p-quaterphenyl, respectively, by using a nickel complex in the presence of bipyridine with DMF as solvent. This type of synthesis was shown to give an improved yield as well as easy preparation and purification of these phenylene oligomers.

Electrochemical reduction of monohalide aromatic compounds with catalytic amount of zero-valent nickel complex leads to corresponding linear dimeric oligophenylens in N,N dimethylacetamide.Effect of applied potential on a mercury pool on the yield of sublimated sexiphenyl under vacuum was studied.Oligophenylens were mainly characterized by infrared spectroscopy.Moreover, electrochemical behavior of parasexiphenyl and of 4 bromo-terphenyl were compared in acetonitrile medium.

Para linked polyphenyls of various molecular weights are conveniently synthesized from p-bis(3-dimethylamino-1-propynyl)arenes and 1-aryl-2-propenyl bromides in moderate yields using a three step, one-pot procedure.
