N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Electric Literature of C12H10N4O2

Removal rate of Pb Ions through functionalized decoration of MOF cavity was written by Afshariazar, Farzaneh;Morsali, Ali;Wang, Jun;Junk, Peter C..

To overcome the challenge of developing a multipurpose adsorbent for effective removal of toxic and carcinogenic PbII ions from aqueous solutions, a made-for-purpose functional group (N1,N2-di(pyridine-4-yl)oxalamide) was rationally designed and incorporated into the cavities of a Zn metal-organic framework (MOF), namely, TMU-56. Large enough pore size along with high densities of strong metal chelating sites lead not only to the highest uptake capacity for PbII ions, but also the fastest removal rate that has ever been reported for functionalized MOFs, occurring in just 20 s. Moreover, high concentrations of lead ions favor the ion exchange reaction, resulting in a high degree of metal exchange. In addition, TMU-56 can be a practical adsorbent because of its notable performance in the simultaneous removal of several toxic and carcinogenic heavy metals from wastewater, which has rare precedence. This study involved multiple reactions and reactants, such as N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7Electric Literature of C12H10N4O2).

N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. 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.COA of Formula: C12H10N4O2

Spin-crossover (SCO) complexes with multiple spin states are promising candidates for high-order magnetic storage and multiple switches. Here, by employing the N,N’-4-dipyridyloxalamide (dpo) ligand, the authors synthesize two Hofmann-type metal-organic frameworks (MOFs) [Fe(dpo){Ag(CN)2}2]·3DMF (1) and [Fe(dpo){Ag(CN)2}2]·0.5MeCN·2DEF (2), which exhibit guest dependent four-step SCO behaviors with the sequences of LS → approx.

Therefore, the incorporation of hydrogen-donating/hydrogen-accepting groups into the Hofmann-type MOFs may effectively explore the multi-step SCO materials by tuning hydrogen-bonding interactions.

Four mono- (1–4) and four binuclear N,N’-di-4-pyridyloxalamide-bridged Ru(II) arene (5–8) complexes have been isolated from the reaction of [Ru(η6-benzene)Cl(μ-Cl)]2 or [Ru(η6-toluene)Cl(μ-Cl)]2 with 2-pyridinecarboxylic acid and 6-fluoro-2-pyridinecarboxylic acid. Their structural characterization included IR and NMR spectroscopy and MS spectrometry. The cytotoxic potential of the compounds has been tested by MTT assay in seven human cancer cell lines: alveolar basal adenocarcinoma (A549), large cell lung carcinoma (HTB177), colorectal carcinoma (HCT116), malignant melanoma (A375), prostate adenocarcinoma (PC3), breast carcinoma (MDA-MB-453), cervix adenocarcinoma (HeLa), and one human non-malignant lung fibroblast cell line (MRC-5). Mononuclear complexes 1 and 3 carrying 2-pyridinecarboxylic acid have displayed moderate antiproliferative effect toward HCT116 and HeLa, slightly better in comparison to their binuclear analogs, 5 and 7. The highest activity and cytoselectivity has been observed 1 as it has reduced viability of HCT116 cells 1.5 times more efficiently (IC50 = 27.5 μM), than of the MRC-5 cells (IC50 = 41.3 μM).

Novel arene-ruthenium [2+2] metalla-rectangles I and II were synthesized by self-assembly using dipyridyl amide ligand and arene-ruthenium acceptors (arene: benzoquinone, naphthacenedione) and characterized by NMR spectroscopy and ESI-MS. The solid-state structure of II was determined by x-ray diffraction and shows encapsulated di-Et ether mol. in the rectangular cavity of II. The luminescent II was further used for anion sensing with the amidic linkage serving as a hydrogen-bond donor site for anions and the ruthenium moiety serving as a signaling unit. A UV/visible titration study demonstrated that although II interacts very weakly with common monoanions as well as with flexible dicarboxylate anions such as malonate and succinate, it displays significant binding affinity (K>103 in MeOH) for rigid multi-carboxylate anions such as oxalate, citrate, and tartrate, exhibiting a 1:1 stoichiometry. Probably 1:1 bidentate hydrogen bonding assisted by appropriate geometrical complementarity is mainly responsible for the increased affinity of II towards such anions. A fluorescence titration study revealed a large fluorescence enhancement of II upon binding to multi-carboxylate anions, which can be attributed to the blocking of the photoinduced electron-transfer process from the arene-Ru moiety to the amidic donor in II as a result of hydrogen bonding between the donor and the anion.

The results showed a good correlation with the steric and electronic parameters obtained by quant. structure activity relation (QSAR) studies. In-vitro cytotoxicity studies against four different cell lines showed that the human breast cancer cell lines MCF-7, T47D and cervical cancer cell line HeLa had either higher or similar sensitivities towards 4, 6 and 2, resp., compared to cisplatin.

Anion-recognition studies of a Re(I)-based square containing the dipyridyl-amide ligand was written by Tzeng, Biing-Chiau;Chen, Yen-Fei;Wu, Chia-Chin;Hu, Cho-Chun;Chang, Ya-Ting;Chen, Chang-Kai. And the article was included in New Journal of Chemistry in 2007.Recommanded Product: N1,N2-Di(pyridin-4-yl)oxalamide The following contents are mentioned in the article:

The mol. square [Re(CO)3Cl(L)]4 (1) containing the dipyridyl-amide ligand, N,N’-4-dipyridyloxalamide (L), was constructed from Re(CO)5Cl and L for the purpose of anion-recognition studies. Upon addition of fluoride anions to a THF solution of 1, a remarkable spectral change is observed, and indeed a new absorption band grows at ∼348 nm. The authors reasoned that upon addition of fluoride, the hydrogen bonds between F– and -NH groups of L would first form and increase the electron densities of nitrogen atoms. This in turn increases the conjugation throughout the L ligand, which is responsible for the new growing absorption band. Finally, a proton-transfer process occurs upon addition of excess F– anions, corroborated by the 1H NMR titration experiment due to the occurrence of HF2–. The binding constants based on a 1:1 complex (1-X–, X– = anions) follow the order: F– > CN– > OAc– > Cl– > Br–, PF6–, BF4–, ClO4–, NO3– and HSO4–. The most electroneg. F– anion shows the largest binding constant, followed by CN–, OAc– and Cl– anions. The less electroneg. Br– anion and bigger PF6–, BF4–, ClO4–, NO3– and HSO4– anions do not show any binding affinity with 1. The control titrations carried out using L and the same series of anions showed that the basicity of anions also possibly lends some contribution to the sensing events. However, the binding affinity of 1 toward various anions can be mostly correlated with the electronegativity as well as cavity size of the mol. square, and hence 1 can be expected to be a sensor for F–.
