Abstract

Oligomeric 2,5-thienylenes and 3-methyl-2,5-thienylenes have been synthesized by NiCl₂(dppp)(dppp = Ph₂PCH₂CH₂CH₂PPh₂) coupling of Grignard compounds with the appropriate bromothiophene; u.v. spectra and oxidation potentials of the oligomers are dicussed in terms of coplanarity of the oligomeric species.
