Allgemeine Beschreibung

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

Anwendung

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.

Asymmetric reduction of 2,6-diacylpyridines with B-chlorodiisopinocampheylborane provides the corresponding C(2)-symmetric diols in very high de and ee. Asymmetric allylboration of 2,6-pyridinedicarboxaldehyde and 2,5-thiophenedicarboxaldehyde provides the corresponding bis-homoallylic alcohols in very high de and ee. These optically pure diols were converted

New symmetrical arylene bisimide derivatives formed by using electron-donating-electron-accepting systems were synthesized. They consist of a phthalic diimide or naphthalenediimide core and imine linkages and are end-capped with thiophene, bithiophene, and (ethylenedioxy)thiophene units. Moreover, polymers were obtained from a new
