General description

2,5-Thiophenedicarboxaldehyde can be prepared from 2,5-bis(chloromethyl)thiophene by the application of Kröhnke′s method.

Application

2,5-Thiophenedicarboxaldehyde may be employed in the following studies:
  • Asymmetric synthesis of bis-homoallylic alcohols.
  • Synthesis of new symmetrical arylene bisimide derivatives.
  • As dialdehyde monomer in the synthesis of silicon-containing poly(p-phenylenevinylene)-related copolymers having uniform p-conjugated segment regulated by organosilicon units.
  • Synthesis of 2,5-bis[2-(5-N-isopropylamidino)benzimidazoyl]thiophene hydrochloride.
