Abstract

An iterative strategy for the synthesis of new sulfur‐functionalized oligothiophenes by Suzuki or Stille cross‐coupling reactions was applied to the reaction of 4‐bromo‐tert‐butylphenylthioether with thiophene derivatives. The planarity of the oligothiophenes obtained was confirmed by the single‐crystal X‐ray structure analysis of 2‐(4′‐tert‐butylthiophenyl)thiophene, which shows a potentially large electronic conjugation length. © 2004 Wiley Periodicals, Inc.
