It is well known fact that the bonding occurs at oxygen atom in the Amides compounds In order to prove this fact we have considered eighteen Amides compounds Present study deals to calculate their Eigen value using Quantum Mech. descriptors via Cache software. With the help of Eigen values, the concentrations of electrons on oxygen and nitrogen atoms of Amides compounds have been calculated In Amides compounds, the sum of contributions of p-orbitals of oxygen atom in the formation of MOs is smaller as compared to other atoms. This indicates that the bonding takes place at oxygen atom.

From this literature《Quantum mechanical study of coordination ability of amides using eigen value parameters》,we know some information about this compound(1452-77-3)Quality Control of Picolinamide, but this is not all information, there are many literatures related to this compound(1452-77-3).

Author is Nandhini, Raja; Venkatachalam, Galmari.

Ruthenium(II) complexes of the general formula [Ru(η6-p-cymene)(Cl)(L1-5)] (L = O, N-donors of biphenylazo derivatives), were synthesized via reacting 2-(biphenylazo)phenols and 1-(biphenylazo)naphthol ligands with [{η6-(p-cymene)RuCl}2(μ-Cl)2]. The synthesized complexes could act as an efficient, reusable homogeneous catalyst for transformation of aldehydes to the corresponding primary amides ArC(O)NH2 [Ar = Ph, 4-MeC6H4, 2-pyridyl, etc.] in the presence of NH2OH·HCl, thus resulted an expansion of Beckmann rearrangement. They also effectively catalyzed the transfer hydrogenation reaction of various ketones with KOH in presence of 2-propanol to afford RCHOHR1 [R = Et, n-Pr, Ph, 4-MeOC6H4; R1 = Me, Ph; R1R2 = (CH2)5, (CH2)6].

Application In Synthesis of 7-Bromo-5-nitro-1H-indole. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 7-Bromo-5-nitro-1H-indole, is researched, Molecular C8H5BrN2O2, CAS is 87240-07-1, about Novel Pyrrolopyridone Bromodomain and Extra-Terminal Motif (BET) Inhibitors Effective in Endocrine-Resistant ER+ Breast Cancer with Acquired Resistance to Fulvestrant and Palbociclib. Author is Li, Yangfeng; Zhao, Jiong; Gutgesell, Lauren M.; Shen, Zhengnan; Ratia, Kiira; Dye, Katherine; Dubrovskyi, Oleksii; Zhao, Huiping; Huang, Fei; Tonetti, Debra A.; Thatcher, Gregory R. J.; Xiong, Rui.

Acquired resistance to fulvestrant and palbociclib is a new challenge to treatment of estrogen receptor pos. (ER+) breast cancer. ER is expressed in most resistance settings; thus, bromodomain and extra-terminal protein inhibitors (BETi) that target BET-amplified ER-mediated transcription have therapeutic potential. Novel pyrrolopyridone BETi leveraged novel interactions with L92/L94 confirmed by a cocrystal structure of 27 with BRD4. Optimization of BETi using growth inhibition in fulvestrant-resistant (MCF-7:CFR) cells was confirmed in endocrine-resistant, palbociclib-resistant, and ESR1 mutant cell lines. 27 was more potent in MCF-7:CFR cells than six BET inhibitors in clin. trials. Transcriptomic anal. differentiated 27 from the benchmark BETi, JQ-1, showing downregulation of oncogenes and upregulation of tumor suppressors and apoptosis. The therapeutic approach was validated by oral administration of 27 in orthotopic xenografts of endocrine-resistant breast cancer in monotherapy and in combination with fulvestrant. Importantly, at an equivalent dose in rats, thrombocytopenia was mitigated.

The heterogeneous catalysis of the hydration of nitriles to amides is a process of great industrial relevance in which cerium(IV) oxide (also referred to as ceria) has shown an outstanding catalytic performance. The use of non-supported ceria nanoparticles is related to difficulties in the purification of the product and the recovery and recyclability of the catalyst. Therefore, in this work, ceria nanoparticles are supported on a polymer matrix either by synthesizing polymer particles by so-called Pickering miniemulsions while using ceria nanoparticles as emulsion stabilizers or, as a comparison, by in-situ crystallization on preformed polymer particles. The former strategy presents significant advantages over the latter in terms of time and consumption of resources, and it facilitates an easier scale-up of the process. In both strategies, the incorporation of a magnetoresponsive core within the polymer matrix allows the recovery and the recycling of the catalyst by simple application of a magnetic field and offers an enhancement of the catalytic efficiency.

From this literature《Magnetically enhanced polymersupported ceria nanocatalysts for the hydration of nitriles》,we know some information about this compound(1452-77-3)Recommanded Product: 1452-77-3, but this is not all information, there are many literatures related to this compound(1452-77-3).

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Chalcogen bonding and liquid crystallinity: Understanding the anomalous behaviour of the 4′-(alkylthio)[1,1′-biphenyl]-4-carbonitriles (nSCB), published in 2022-01-15, which mentions a compound: 693-67-4, mainly applied to alkylthio biphenyl carbonitrile preparation chalcogen bonding liquid crystallinity, SDS of cas: 693-67-4.

The synthesis and characterization of the first eleven members of the 4′-(alkylthio)[1,1′-biphenyl]-4-carbonitriles, I [n = 1, 2, 3, etc.] was reported. All eleven members I showed monotropic liquid crystal behavior. The first six members were exclusively nematogenic, the seventh member showed nematic and smectic A phases and the higher homologues only smectic A behavior. A comparison of their transitional behavior with that of the corresponding alkyl and alkyloxy-cyanobiphenyls revealed a new pattern of behavior. Specifically, the nematic-isotropic transition temperatures showed a large decrease on passing from the methylthio to ethylthio homologues. This unexpected behavior was interpreted in terms of chalcogen bonding.

Safety of cis-Dichlorobis(pyridine)platinum(II). The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Rotation and conformation of purine ligands in cis-bis(6-oxopurine)platinum compounds. Author is Marcelis, A. T. M.; Van der Veer, J. L.; Zwetsloot, J. C. M.; Reedijk, J..

cis-[PtL2L12]2+ (L = guanosine, 9-methylhypoxanthine, L1 = Me-substituted 1,3-propanediamines, py, α-picoline, 2,2′-bipyridine, 1,2-bis(pyridin-2-yl)ethane) were prepared and studied by NMR. Rotation of L about their Pt-N7 bonds is fast on the NMR time scale, when no Me groups are present on the nitrogens of the 1,3-propanediamine ligands. Rotation is slow when 2 Me groups are present on 1 N of a 1,3-propanediamine chelate. A single Me group on a N hardly seems to interfere with this rotation. Coordinated pyridines do not hinder rotation. In compounds containing 2-methylpyridine ligands, the rotation of the pyridines is slow at room temperature, but becomes fast at higher temperatures Rotation of L, however, is fast on the NMR time scale from -30 to +90°. In compounds containing 1,2-bis(pyridin-2-yl)ethane, rotation of L is slow at low temperatures, but becomes fast at room temperature Furthermore, the results obtained with these compounds show that the purines are preferentially oriented in a head-to-tail arrangement.
