N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Formula: C12H10N4O2

Donor-Flexible Bis(pyridylidene amide) Ligands for Highly Efficient Ruthenium-Catalyzed Olefin Oxidation was written by Salzmann, Kevin;Segarra, Candela;Albrecht, Martin. And the article was included in Angewandte Chemie, International Edition in 2020.Formula: C12H10N4O2 The following contents are mentioned in the article:

An exceptionally efficient ruthenium-based catalyst for olefin oxidation was designed by exploiting N,N’-bis(pyridylidene)oxalamide (bisPYA) as a donor-flexible ligand. The dynamic donor ability of the bisPYA ligand, imparted by variable zwitterionic and neutral resonance structure contributions, paired with the redox activity of ruthenium provided catalytic activity for Lemieux-Johnson-type oxidative cleavage of olefins to efficiently prepare ketones and aldehydes. The ruthenium bisPYA complex significantly outperforms state-of-the-art systems and displays extraordinary catalytic activity in this oxidation, reaching turnover frequencies of 650,000 h-1 and turnover numbers of several millions. This study involved multiple reactions and reactants, such as N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7Formula: C12H10N4O2).
