Application

trans-1,2-Bis(tributylstannyl)ethene can be used to prepare:
  • Polyarylenevinylene polymers having triphenylamine core moieties.
  • Two (E)-2-(2-(thiophen-2-yl)vinyl)thiophen based copolymers through Pd-catalyzed Stille coupling reaction.
  • Vinylstannanes by reacting with aryl halides, which in turn can be used in the synthesis of substituted pyridines.

A reliable synthetic protocol toward a series of fused chalcogenopheno[1]benzochalcogenophene (CBC) building blocks was developed based on a Fiesselmann reaction. The obtained CBC units were applied in McMurry and Stille coupling reactions toward symmetric regioisomeric ene-linked dimers. These π-conjugated compounds
