Beschreibung

Anwendung

trans,trans-1,4-Diphenyl-1,3-butadiene can be used as a reactant to synthesize:

• 2,5-diphenylthiophene by oxidation reaction with potassium sulfide and DMSO.
• 2-[(3E)-4-Phenyl-2-(phenylmethyl)-3-buten-1-yl]furan via nickel catalyzed hydrobenzylation reaction with furfural in the presence of N₂H₄.

It can also be used as a ligand to prepare silver(I) coordination polymers by reacting with silver(I) salts.
