Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Recommanded Product: 91-02-1

Synthesis of the multidentate coordinated chelate N3C-H2, composed of a linked functional pyridyl pyrazole fragment plus a peripheral Ph and pyridyl unit, was obtained using a multistep protocol. Preparation of Ir(III) metal complexes bearing a N3C chelate in the tridentate (榄?sup>3), tetradentate (榄?sup>4), and pentadentate (榄?sup>5) modes was executed en route from two nonemissive dimer intermediates [Ir(榄?sup>3-N3CH)Cl2]2 (1) and [Ir(榄?sup>4-N3C)Cl]2 (2). Next, a series of mononuclear Ir(III) complexes with the formulas [Ir(榄?sup>4-N3C)Cl(py)] (3), [Ir(榄?sup>4-N3C)Cl(dmap)] (4), [Ir(榄?sup>4-N3C)Cl(mpzH)] (5), and [Ir(榄?sup>4-N3C)Cl(dmpzH)] (6), as well as diiridium complexes [Ir2(榄?sup>5-N3C)(mpz)2(CO)(H)2] (7) and [Ir2(榄?sup>5-N3C)(dmpz)2(CO)(H)2] (8), were obtained upon treatment of dimer 2 with pyridine (py), 4-dimethylaminopyridine (dmap), 4-methylpyrazole (mpzH), and 3,5-dimethylpyrazole (dmpzH), resp. These Ir(III) metal complexes were identified using spectroscopic methods and by x-ray crystallog. anal. of representative derivatives 3, 5, and 7. Their photophys. and electrochem. properties were investigated and confirmed by the theor. simulations. Notably, green-emitting organic light-emitting diode (OLED) on the basis of Ir(III) complex 7 gives a maximum external quantum efficiency up to 25.1%. This result sheds light on the enormous potential of this tetradentate coordinated chelate in the development of highly efficient iridium complexes for OLED applications. Preparation of Ir(III) complexes bearing tailor-made multidentate N3C chelate are reported, from which a green-emitting OLED with a maximum EQE of 25.1% was successfully fabricated using diiridium complex 7. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Recommanded Product: 91-02-1).

Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Formula: C12H9NO

Effect of Activation Methods of Molecular Sieves on Ketimine Synthesis was written by Yasukawa, Tomohiro;Nakajima, Hanako;Masuda, Ryusuke;Yamashita, Yasuhiro;Kobayashi, Shu. And the article was included in Journal of Organic Chemistry.Formula: C12H9NO This article mentions the following:

Although the use of mol. sieves for imine synthesis is a common protocol, there have been no comprehensive studies on heat-drying methods, and this can be crucial for reproducibility. It was found that mol. sieve 5A dried at 160 鎺矯 for 5 h under vacuum efficiently promoted the condensation of various ketones RC(O)R1 (R = n-Pr, Ph, 4-flurophenyl, etc.; R1 = Ph, Me, pyridin-2-yl, etc.) and amines R2NH2 (R2 = Ph, 4-chlorophenyl, cyclohexyl, etc.) to afford even relatively bulky ketimines RC(R1)=NR2. Several control experiments and analyses revealed that only a small amount of Bronsted acid sites was important for the activity, rather than dehydration ability. Other types of mol. sieves could be utilized for the reaction after treatment with water followed by heat drying. A continuous-flow acetalization reaction of alcs. using the activated mol. sieve 5A was also demonstrated. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Formula: C12H9NO).

Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the 蟺-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the 蟽 bonds. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Product Details of 91-02-1

Scandium(III) Triflate Catalyzed Direct Synthesis of N-Unprotected Ketimines was written by Kondo, Yuta;Kadota, Tetsuya;Hirazawa, Yoshinobu;Morisaki, Kazuhiro;Morimoto, Hiroyuki;Ohshima, Takashi. And the article was included in Organic Letters in 2020.Product Details of 91-02-1 This article mentions the following:

N-Unprotected ketimines are useful substrates and intermediates for synthesizing valuable nitrogen-containing compounds, but their potential applicability is limited by the available synthetic methods. To address this issue, we report a scandium(III) triflate catalyzed direct synthesis of N-unprotected ketimines. Using com. available reagents and Lewis acid catalysts, ketones were directly transformed into the corresponding N-unprotected ketimines in high yields with broad functional group tolerance, even in multigram scales. The reactions were readily applicable for one-pot synthesis of important compounds such as a glycine Schiff base without isolation of N-unprotected ketimine intermediates. Preliminary mechanistic studies to clarify the reaction mechanism are also described. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Product Details of 91-02-1).
