The article was written by Kurpik, Gracjan; Walczak, Anna; Goldyn, Mateusz; Harrowfield, Jack; Stefankiewicz, Artur R.. The article contains the following contents:

A wide range of functionalized pyridine ligands were employed to synthesize a variety of Pd(II) complexes [PdL4](NO3)2 and [PdL2Y2], where L = 4-X-py and Y = Cl- or NO3-. Their structures were unambiguously established via anal. and spectroscopic methods in solution (NMR spectroscopy and mass spectrometry) as well as in the solid state (x-ray diffraction). This in-depth characterization showed that the functionalization of ligand mols. with groups of either electron-withdrawing or -donating nature (EWG and EDG) results in significant changes in the physicochem. properties of the desired coordination compounds Downfield shifts of signals in the 1H NMR spectra were observed upon coordination within and across the complex families, clearly indicating the relation between NMR chem. shifts and the ligand basicity as estimated from pKa values. A detailed crystallog. study revealed the operation of a variety of weak interactions, which may be factors explaining aspects of the solution chem. of the complexes. The Pd(II) complexes are efficient and versatile precatalysts in Suzuki-Miyaura and Heck cross-coupling reactions within a scope of structurally distinct substrates, and factors were identified that have contributed to efficiency improvement in both processes. In the experiment, the researchers used many compounds, for example, 4-Acetylpyridine(cas: 1122-54-9Related Products of 1122-54-9)

In 2022,Jin, Yaping; Wang, Ting; Che, Xuefu; Dong, Jianhao; Li, Qingfeng; Yang, Jingshuai published an article in Journal of Power Sources. The title of the article was 《Poly(arylene pyridine)s: New alternative materials for high temperature polymer electrolyte fuel cells》.Synthetic Route of C7H7NO The author mentioned the following in the article:

Developing high-performance and low-cost high temperature polymer exchange membranes (HT-PEMs) is a huge challenge to fuel cells. Here, two poly(arylene pyridine)s (PTAP and PBAP) are synthesized through a simple one-step Friedel-Crafts polymerization of 4-acetylpyridine and para-terphenyl/biphenyl. Both PTAP and PBAP exhibit superior organic solubility and excellent thermal stability. Owing to pyridine groups, PBAP and PTAP membranes display excellent phosphoric acid (PA) absorption capability. The PTAP membrane achieves a PA uptake of 220% after immersing in 85 wt% PA solution at 100 °C, and a high conductivity of 0.102 S cm-1 at 180 °C. Specially, PBAP and PTAP also possess remarkable chem. stability. After 450 h Fenton test, the PTAP membrane still exhibits a high PA uptake of 200% and high conductivity of 0.086 S cm-1. A single H2-O2 cell based on the PTAP/220% membrane shows a peak power d. of 743 mW cm-2 at 180 °C without any back pressure, which also displays excellent durability under 200 mA cm-2 and 400 mA cm-2 at 160 °C. Thus, this work develops a facile, cost effective and up-scalable synthetic route of alternative HT-PEM under mild conditions, comparing with the state-of-the-art polybenzimidazole (PBI) membrane.4-Acetylpyridine(cas: 1122-54-9Synthetic Route of C7H7NO) was used in this study.

Computed Properties of C7H7NOIn 2021 ,《Formate-driven catalysis and mechanism of an iridium-copper complex for selective aerobic oxidation of aromatic olefins in water》 was published in Chemical Science. The article was written by Shimoyama, Yoshihiro; Kitagawa, Yasutaka; Ohgomori, Yuji; Kon, Yoshihiro; Hong, Dachao. The article contains the following contents:

A hetero-dinuclear IrIII-CuII complex with two adjacent sites was employed as a catalyst for the aerobic oxidation of aromatic olefins driven by formate in water. An IrIII-H intermediate, generated through formate dehydrogenation, was revealed to activate terminal aromatic olefins to afford an Ir-alkyl species, and the process was promoted by a hydrophobic [IrIII-H]-[substrate aromatic ring] interaction in water. The Ir-alkyl species subsequently reacted with dioxygen to yield corresponding Me ketones and was promoted by the presence of the CuII moiety under acidic conditions. The IrIII-CuII complex exhibited cooperative catalysis in the selective aerobic oxidation of olefins to corresponding Me ketones, as evidenced by no reactivities observed from the corresponding mononuclear IrIII and CuII complexes, as the individual components of the IrIII-CuII complex. The reaction mechanism afforded by the IrIII-CuII complex in the aerobic oxidation was disclosed by a combination of spectroscopic detection of reaction intermediates, kinetic anal., and theor. calculations After reading the article, we found that the author used 4-Acetylpyridine(cas: 1122-54-9Computed Properties of C7H7NO)

《Chiral Imidazo[1,5-a]pyridine-Oxazolines: A Versatile Family of NHC Ligands for the Highly Enantioselective Hydrosilylation of Ketones》 was published in Organometallics in 2020. These research results belong to Chinna Ayya, Swamy .P.; Varenikov, Andrii; de Ruiter, Graham. SDS of cas: 1122-54-9 The article mentions the following:

Herein the authors report the synthesis and application of a versatile class of N-heterocyclic carbene ligands based on an imidazo[1,5-a]pyridine-3-ylidine backbone that is fused to a chiral oxazoline auxiliary. The key step in the synthesis of these ligands involves the installation of the oxazoline functionality via a microwave-assisted condensation of a cyano-azolium salt with a wide variety of 2-amino alcs. The resulting chiral bidentate NHC-oxazoline ligands form stable complexes with Rh(I) that are efficient catalysts for the enantioselective hydrosilylation of structurally diverse ketones. The corresponding secondary alcs. are isolated in good yields (typically >90%) with good to excellent enantioselectivities (80-95% ee). The reported hydrosilylation occurs at ambient temperatures (40°), with excellent functional group tolerability. Even ketones bearing heterocyclic substituents (e.g., pyridine or thiophene) or complex organic architectures are hydrosilylated efficiently, which is discussed further.
