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 [Ir2(μ2-oxamidato-N,N′,O,O′)(ptpy)4], ptpy = 2-(p-tolyl)pyridinato.

The conformational properties of the oxalamide group and crystal structure of several polyoxalamides have been investigated by computational methods. First, a detailed quantum mechanical study of the conformational preferences of N,N'-dimethyloxalamide is reported. Results, which were obtained at the MP2/6-31G(d)

A comparison of the molecular structure of related nickel(II) complexes of the open-chain and 13-membered macrocyclic oxamide-derived ligands NiL(1).4H2O and NiL(2).3H2O revealed that the formation of an additional 6-membered chelate ring in the complex results in rather small changes in

Light scattering (LS) signals have been applied for analytical detections, but the selectivity is poor. In order to improve the selectivity, pre-separation or new machines are generally considered. Differing from these methods, we synthesized a highly selective oxamide ligand, N',N'-bis
