Abstract

α-Quaterthiophene (1), α-sexithiophene (2), and α-octithiophene (3) (the highest member of α-oligothiophenes ever synthesized) were prepared from α-bithiophene, α-terthiophene, and α-quaterthiophene, respectively, via monobromination with N-bromosuccinimide followed by reductive coupling reaction with an activated nickel (0) reagent.
