Related Products of 28903-71-1. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about Photocatalyst-controlled and visible light-enabled selective oxidation of pyridinium salts. Author is Peng, Xiang-Jun; He, Hai-Ping; Liu, Qian; She, Kun; Zhang, Bao-Qi; Wang, Heng-Shan; Tang, Hai-Tao; Pan, Ying-Ming.

This study proposed two different methods of photocatalytic-controlled and visible light-induced selective oxidation of pyridiniums with air as the terminal oxidant. The key to these transformations was to choose the appropriate light source and photocatalyst. Pyridiniums were successfully converted into pyrroles through oxygen-mediated cycloaddition, proton-coupled electron transfer (PCET), pyridine ring opening, and recyclization. The other route was that pyridiniums selectively form 4-carbonyl pyridines through free radical rearrangement/aerobic oxidation under the catalysis of cobalt (II).

A solvent-free and environment-friendly process for the oxidation of 4-ethylnitrobenzene to 4-nitroacetophenone promoted by metalloporphyrins was developed in a pressure reactor using O2 as a clean oxidant. The activities and reaction selectivities of the metalloporphyrins could be significantly affected by their central metal ions as well as the nature and position of the substituted groups, which were systematically investigated by employing more than 60 metalloporphyrins. Generally, the Fe(III)- and Mn(II)-porphyrins exhibited high activities. Moreover, metalloporphyrins with electron-withdrawing substituents on the para-positions of the Ph rings showed activities in the order T(p-Br)PPM < T(p-Cl)PPM < T(p-F)PPM. The substituent position effect on the activities of T(o-Cl)PPM > T(m-Cl)PPM > T(p-Cl)PPM and T(o-OMe)PPM < T(m-OMe)PPM < T(p-OMe)PPM were observed Furthermore, selectivities over 90.0% and a TON of 5370 could be achieved for the desired ketone. Especially, the T(p-Cl)PPMn demonstrated a selectivity of up to 93.6% and a conversion of 51.9% with only 3.3% acid and no alc. observed, and the selectivity was nearly the same for a large-scale experiment (100 g).

Author is Sakhaei, Zeinab; Kundu, Subrata; Bertke, Jeffery A.; Warren, Timothy H..

Nitrite is involved in a plethora of biol. phenomena that includes tyrosine nitration associated with neurodegenerative disorders and gastric phenol metabolism Reaction of the β-diketiminato model complex [Cl2NNF6]Cu(κ2-O2N) (I) with phenols outlines the coupled generation of NO with phenol oxidation by nitrite at copper(II). Kinetic studies support nucleophilic attack of the hydroxyl group of phenols ArOH on the bound nitrite in [CuII](κ2-O2N) to give the copper(II) hydroxide [CuII]OH along with the O-nitrosated phenol ArONO that ultimately leads to the corresponding biphenol or o-nitrophenol. The especially electron-rich antioxidant α-tocopherol (vitamin E) quickly generates NO upon interaction with [CuII](κ2-O2N). X-ray anal. of the oxidation products of the α-tocopherol analog PMC reveal formation of an elusive O-quinone methide bound to [CuI], revealing two electron oxidation of PMC by [CuII](κ2-O2N). These studies illustrate anaerobic pathways that generate NO from nitrite at copper(II) sites that result in phenol oxidation

Synthetic Route of C10H8ClN4NaO2S. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Sodium ((4-aminophenyl)sulfonyl)(6-chloropyrazin-2-yl)amide, is researched, Molecular C10H8ClN4NaO2S, CAS is 23307-72-4, about A self-assembly pipette tip graphene solid-phase extraction coupled with liquid chromatography for the determination of three sulfonamides in environmental water. Author is Sun, Ning; Han, Yehong; Yan, Hongyuan; Song, Yanxue.

A sensitive, economical, and miniaturized self-assembly pipet tip graphene solid-phase extraction (PT-G-SPE) coupled with liquid chromatog. fluorescence detection (LC-FD) was developed for rapid extraction and determination of three sulfonamide antibiotics (SAs) in environmental water samples. The PT-G-SPE cartridge, assembled by packing 1.0 mg of graphene as sorbent into a 100 μL pipet tip, showed high adsorption capacity for the SAs owing to the large surface area and unique structure of graphene. The factors that affected the extraction efficiency of PT-G-SPE, including sample volume, pH, sorbent amount, washing solvent and eluent solvent were optimized. Good linearity for SAs was obtained in a range of 2-4000 pg mL-1 with correlation coefficients (r2) ≥0.9993. The recoveries of the SAs at three spiked levels ranged from 90.4 to 108.2% with RSD ≤6.3%. In comparison with other sorbents such as C18, HLB, SCX, PCX, and multiwalled carbon nanotubes, one advantage of using graphene as sorbent of pipet tip solid-phase extraction (PT-SPE) was that PT-G-SPE could adsorb larger sample volume (10 mL) at a small amount of sorbent (1 mg) and low solvent consumption with good extraction efficiency, which not only increased the fraction of analytes to LC and the sensitivity of SAs determination, but also reduced the cost and pollution.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Robinson, Thomas P.; Price, Richard D.; Davidson, Matthew G.; Fox, Mark A.; Johnson, Andrew L. researched the compound: Mesitylcopper(I)( cas:75732-01-3 ).Product Details of 75732-01-3.They published the article 《Why are the {Cu4N4} rings in copper(I) phosphinimide clusters [Cu{μ-N:PR3}]4 (R = NMe3 or Ph) planar?》 about this compound( cas:75732-01-3 ) in Dalton Transactions. Keywords: crystal structure optimized tetrameric cyclic copper phosphinimide preparation; mol structure optimized tetrameric cyclic copper phosphinimide preparation. We’ll tell you more about this compound (cas:75732-01-3).

The Cu phosphinimide complexes [Cu{μ-N:PR3}]4 (1, R = NMe2 and 2, R = Ph) were obtained in good yields from the reactions of Cu[Mes] (Mes = mesityl, C6H2Me3-2,4,6) with the corresponding iminophosphoranes, HNPR3. The mol. structures of 1 and 2 reveal planar eight-membered {Cu4N4} rings which contrasts with the saddle-shaped {M4N4} rings found in related metal phosphinimide complexes. According to computations, there is negligible aromaticity in the planar {Cu4N4} rings in 1 and 2 and the saddle shape observed in related {M4N4} rings is due to steric factors.

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 Copper(I) Complexes of a Heavily Fluorinated β-Diketiminate Ligand: Synthesis, Electronic Properties, and Intramolecular Aerobic Hydroxylation, published in 2003-11-17, which mentions a compound: 75732-01-3, mainly applied to fluorinated copper diketiminate preparation oxidation crystal mol structure, Application of 75732-01-3.

The aza-Wittig reaction between Arf-N:PPh3 [Arf = 3,5-(CF3)2C6H3] and 1,1,1,5,5,5-hexafluoro-2,4-pentanedione affords a new, highly fluorinated β-diketimine, 1. Metalation by mesitylcopper(I) in benzene gives rise to the Cu(I) β-diketiminate as its η2-benzene adduct, 2a. Cu(I) carbonyl complexes of 1, and of three less-fluorinated analogs, were generated in situ and compared by IR spectroscopy; the two backbone CF3 groups exert a stronger electronic influence than the four N-aryl CF3 groups. Dinuclear adduct 2b reacts readily with O2, leading to ortho-hydroxylation of a ligand N-Arf group.

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 Impact of Surface Chemistry on Copper Deposition in Mesoporous Silicon, published in 2016-08-02, which mentions a compound: 75732-01-3, mainly applied to surface chem copper deposition mesoporous silicon, Category: iodides-buliding-blocks.

An easy, efficient, and safe process is developed to metalize mesoporous Si (PSi) with Cu from the decomposition of a solution of mesitylcopper (CuMes) in an imidazolium-based ionic liquid (IL), [C1C4Im][NTf2]. The impregnation of a solution of CuMes in IL affords the deposition of metallic islands not only on the surface but also deep within the pores of a mesoporous Si layer with small pores <10 nm. Therefore, this process is well suited to efficiently and completely metalize PSi layers. An in-depth mechanistic study shows that metal deposition is due to the reduction of CuMes by surface silane groups rather than by Si oxidation as observed in aqueous or H2O-containing media. This could open a new route to the chem. metalization of PSi by less-noble metals difficult to attain by a conventional displacement reaction.
