Application

1,4-Diiodobenzene was used in:
  • total synthesis of martinellic acid, a naturally occurring bradykinin receptor antagonist
  • preparation of 1,4-bis(p-R-phenylethynyl)benzenes via Pd11/Cu1catalyzed cross-coupling reaction
  • synthesis of 1,4-diiodo-2,5-didodecylbenzene, starting reagent for the preparation of oligo(1,4-phenylene ethynylene)s
  • surface-mediated synthesis of epitaxially aligned and separated polyphenylene lines on Cu(110) via Ullmann dehalogenation reaction
