Application

Oxamide can be used:
  • As a precursor for the synthesis of ligands such as bis(benzimidazole) and Schiff base ligands formed by condensation with furfural.
  • Carbon nitride (g-C3N4) nanotubes by self-assembly polymerization with urea.
  • As a bridging ligand for the synthesis of binuclear IrIII complex [Ir22-oxamidato-N,N′,O,O′)(ptpy)4], ptpy = 2-(p-tolyl)pyridinato.
