Aplicação

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.

Pathogen-specific and overall infection burden may contribute to atherosclerosis and cardiovascular disease (CVD), but the effect of infection severity and timing is unknown. We investigated whether childhood infection-related hospitalisation (IRH, a marker of severity) was associated with subsequent adult CVD
