General Description

2-Bromopyridine N-oxide is a chemical compound primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is a derivative of pyridine and is commonly used in organic synthesis as a building block for various chemical reactions. 2-Bromopyridine N-oxide has also been studied for its potential use as a reagent in chemoselective transformations and as a ligand in metal-catalyzed reactions. Additionally, it has been found to exhibit antimicrobial and antifungal properties, and has been investigated for its potential as a therapeutic agent for treating certain diseases. However, it is important to handle 2-Bromopyridine N-oxide with care, as it is a hazardous material and should only be handled by trained professionals in a controlled laboratory setting.

Check Digit Verification of cas no

The CAS Registry Mumber 14305-17-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,0 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14305-17:
(7*1)+(6*4)+(5*3)+(4*0)+(3*5)+(2*1)+(1*7)=70
70 % 10 = 0
So 14305-17-0 is a valid CAS Registry Number.

Development of a novel antidiabetic zinc complex with an organoselenium ligand at the lowest dosage in KK-Ay mice

Fujimoto, Shigeyuki,Yasui, Hiroyuki,Yoshikawa, Yutaka

, p. 10 - 15 (2013)

Diabetes mellitus (DM) is a considerably diagnosed metabolic disease and a serious problem worldwide. We prepared various zinc complexes and studied their potential for use as new antidiabetic agents. In this study, we synthesized a seleniferous zinc complex, di(2-selenopyridine-N-oxidato)zinc(II) ([ZPS]) that has a Zn(Se2O2) coordination mode. Analyses of structure-activity relationships between its insulin-like activity and the coordination mode of [ZPS]-related complexes showed that it had high insulin-like activity. Hypoglycemic effects of [ZPS] on type 2 diabetic KK-Ay mice were exerted at the lowest dose administered (1.25-2.5 mg Zn/kg body weight), unlike previously synthesized zinc complexes. Furthermore, [ZPS] afforded us a new advantage; we were able to investigate the tissue distribution of the ligand by measuring the amount of selenium in the organs of [ZPS]-treated mice. Gastrointestinal absorption and tissue penetration of zinc derived from [ZPS] in ddY mice, which was monitored using an isotope tracer technique, was significantly increased compared to that of ZnCl2. These results suggest that [ZPS] has superior antidiabetic effects compared to previously reported zinc complexes, and is thus a potential novel antidiabetic agent that facilitates the possibility of organoselenium ligands as new metal delivery systems for treating DM.

Method for preparing sulfone and N-oxygen compound by using green and efficient oxidation system

-

Paragraph 0042-0044, (2021/01/29)

The invention discloses a method for preparing sulfone and N-oxygen compound by using a green and efficient oxidation system. The method comprises the following steps of: by using a tertiary amine compound or aromatic thioether or fatty thioether compound as a raw material, H2O2 as an oxidant, methanol as a reaction solvent and potassium carbonate as an alkali, introducing sulfuryl fluoride 5O2F2gas as an accelerator; performing stirring at room temperature under a sealed condition for oxidation reaction; and after finishing the reaction, filtering to remove solid potassium carbonate, dryingto remove water, filtering to obtain a crude product, and finally carrying out column chromatography separation to obtain a pure product. Tertiary amine is oxidized into an N-oxygen compound, and thethioether is oxidized into sulfone. According to the method, the sulfuryl fluoride (SO2F2) which is very cheap and easy to obtain is used as the reaction promoter, green and environment-friendly hydrogen peroxide (H2O2) is used as an oxidizing agent, and so that the yield of the reaction is generally high; after the reaction, byproducts are only water and inorganic salts (SO4 and F) whichare easy to remove and free of pollution, and the green and efficient oxidation system can be realized, and therefore, the method is suitable for large-scale industrial production.

Photocatalytic CO2 Reduction by Trigonal-Bipyramidal Cobalt(II) Polypyridyl Complexes: The Nature of Cobalt(I) and Cobalt(0) Complexes upon Their Reactions with CO2, CO, or Proton

Shimoda, Tomoe,Morishima, Takeshi,Kodama, Koichi,Hirose, Takuji,Polyansky, Dmitry E.,Manbeck, Gerald F.,Muckerman, James T.,Fujita, Etsuko

supporting information, p. 5486 - 5498 (2018/05/17)

The cobalt complexes CoIIL1(PF6)2 (1; L1 = 2,6-bis[2-(2,2′-bipyridin-6′-yl)ethyl]pyridine) and CoIIL2(PF6)2 (2; L2 = 2,6-bis[2-(4-methoxy-2,2′-bipyridin-6′-yl)ethyl]pyridine) were synthesized and used for photocatalytic CO2 reduction in acetonitrile. X-ray structures of complexes 1 and 2 reveal distorted trigonal-bipyramidal geometries with all nitrogen atoms of the ligand coordinated to the Co(II) center, in contrast to the common six-coordinate cobalt complexes with pentadentate polypyridine ligands, where a monodentate solvent completes the coordination sphere. Under electrochemical conditions, the catalytic current for CO2 reduction was observed near the Co(I/0) redox couple for both complexes 1 and 2 at E1/2 = -1.77 and -1.85 V versus Ag/AgNO3 (or -1.86 and -1.94 V vs Fc+/0), respectively. Under photochemical conditions with 2 as the catalyst, [Ru(bpy)3]2+ as a photosensitizer, tri-p-tolylamine (TTA) as a reversible quencher, and triethylamine (TEA) as a sacrificial electron donor, CO and H2 were produced under visible-light irradiation, despite the endergonic reduction of Co(I) to Co(0) by the photogenerated [Ru(bpy)3]+. However, bulk electrolysis in a wet CH3CN solution resulted in the generation of formate as the major product, indicating the facile production of Co(0) and [Co-H]n+ (n = 1 and 0) under electrochemical conditions. The one-electron-reduced complex 2 reacts with CO to produce [Co0L2(CO)] with νCO = 1894 cm-1 together with [CoIIL2]2+ through a disproportionation reaction in acetonitrile, based on the spectroscopic and electrochemical data. Electrochemistry and time-resolved UV-vis spectroscopy indicate a slow CO binding rate with the [CoIL2]+ species, consistent with density functional theory calculations with CoL1 complexes, which predict a large structural change from trigonal-bipyramidal to distorted tetragonal geometry. The reduction of CO2 is much slower than the photochemical formation of [Ru(bpy)3]+ because of the large structural changes, spin flipping in the cobalt catalytic intermediates, and an uphill reaction for the reduction to Co(0) by the photoproduced [Ru(bpy)3]+.
