A series of zinc(II) alkyl complexes I (1a-c, M = ZnEt) stabilized by the C2-chiral bis(oxazolinato) (HR1,R2BOX) ligands [a, R1 = (4S)-tBu, R2 = H; b, R1 = (4S)-Ph, R2 = H; c, R1 = (4R)-Ph, R2 = (5S)-Ph], has been prepared by metalation of the methylenebis(oxazoline) proligands with diethylzinc and structurally characterized. In an excess of HR1,R2BOX proligands, the homoleptic four-coordinate bis-BOX complexes (2a,b, shown as I2, M = 1/2Zn) were isolated; the crowded ligand c did not give bis-BOX complex. The BOC-ethylzinc complexes 1a-c react readily with protic reagents such as acetic acid (HOAc) and methanol (MeOH). From reaction of 1a,b the homoleptic complexes 2a,b were isolated, resulting from redistribution and formation of Zn acetate, whereas the 1c gave acetato-bridged dimer [3c’, shown as I2, R1 = R2 = Ph, M = (μ-AcO)Zn]. From reaction of 1b with MeOH, the methoxy-bridged complex [4b’, shown as I2, R1 = Ph, R2 = H, M = (μ-MeO)Zn] was obtained, via a three-coordinate complex (4c, shown as I, R1 = Ph, R2 = H, M = ZnOMe). The reaction of acetylacetone (acacH) with compounds 1a-c leads straightforwardly to the more stable four-coordinate compounds I [5a-c, M = Zn(acac)]. The potential of these compounds as initiators for the copolymerization of epoxides with CO2 was investigated.

The reaction of nitrous oxide (N2O) with N-heterocyclic olefins (NHOs) results in cleavage of the N-O bond and formation of azo-bridged NHO dimers. The latter represent very electron-rich compounds with a low ionization energy. Cyclic voltammetry studies show that the dimers can be classified as new organic super-electron-donors, with a reducing power similar to what is found for tetraazafulvalene derivatives Mild oxidants are able to convert the neutral dimers into radical cations, which can be isolated. Further oxidation gives stable dications.

A series of Iridium(III) complexes of general formula [Ir(ppy)2(L)]0/+ (ppy = 2-Ph pyridine, L = Schiff base) were synthesized from the dichloro bridged dimeric starting material, [(ppy)2Ir(μ-Cl)2Ir(ppy)2].

Keywords: blue LED ortho selective aminopyridylation alkene aminopyridinium ylide. We’ll tell you more about this compound (cas:1008-89-5).

By utilizing an underexplored reactivity mode of N-aminopyridinium ylides, we developed the visible-light-induced ortho-selective aminopyridylation of alkenes via radical-mediated 1,3-dipolar cycloaddition The photocatalyzed single-electron oxidation of N-aminopyridinium ylides generates the corresponding radical cations that enable previously inaccessible 1,3-cycloaddition with a broader range of alkene substrates. The resulting cycloaddition adducts rapidly undergo subsequent homolytic cleavage of the N-N bond, conferring a substantial thermodn. driving force to yield various β-aminoethylpyridines. Remarkably, amino and pyridyl groups can be installed into both activated and unactivated alkenes with modular control of ortho-selectivity and 1,2-syn-diastereoselectivity under metal-free and mild conditions. Combined exptl. and computational studies are conducted to clarify the detailed reaction mechanism and the origins of site selectivity and diastereoselectivity.

This study presents the removal of triarylmethane dye Bromocresol Green from aqueous solution by the electro-Fenton process. As catalysts five different cations were used: Fe2+, Ce3+, Ni2+, Mn2+, and Co2+. They play crucial roles in the whole process because they react with H2O2 producing hydroxyl radicals that are capable of breaking down dye mols. Based on this, a comparison of catalytic activity of these cations in the electro-Fenton process is made for Bromocresol Green degradation A simple and universal kinetic model is also applied to study the catalytic activity of investigated catalysts. Due to its multidimensionality it is fitted to exptl. data using a genetic algorithm. The procedure of fitting using a genetic algorithm is thoroughly described and demonstrated. The activity of utilized catalysts is compared based on both exptl. and model data revealing that for Bromocresol Green removal all alternative catalysts (Ni2+, Co2+, Ce3+, Mn2+) are better than the typical one (Fe2+, 51.83% degradation). The best catalyst is Co2+ with 78.35% degradation efficiency. Moreover, the adopted kinetic model proved its universality and outlined different interactions between catalysts and dye mols.

There is still a lot of research devoted to this compound(SMILES：CC1=C(Br)C(O)=C(Br)C=C1C2(C3=CC(Br)=C(O)C(Br)=C3C)C4=CC=CC=C4S(O2)(=O)=O)Product Details of 76-60-8, and with the development of science, more effects of this compound(76-60-8) can be discovered.

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 Silver nanoparticles incorporated in dicarboxylic/TEPA modified halloysite nanotubes for the degradation of organic contaminants, published in 2020-11-30, which mentions a compound: 76-60-8, mainly applied to silver nanoparticle dicarboxylic acid TEPA halloysite nanotube organic contaminant, Product Details of 76-60-8.

Silver supported on organo-modified halloysite nanotubes (Ag-HNTX/T) were fabricated through three steps of modifications; (i) functionalization of pristine halloysite nanotubes (HNT) with dicarboxylic acids, namely succinic acid (SA), oxalic acid (OX), or sebacic acid (SB), (ii) addition of tetraethylenepentamine (TEPA), and finally (iii) incorporation of silver particles (Ag). The modification with dicarboxylic acid and TEPA on HNT was proven by the presence of -COOH and -NH functional groups in the FTIR spectra. Upon introduction of Ag particles on the organo-modified HNT, the Ag-HNTSA/T sample exhibits UV-DRS absorption at 460 nm, corresponding to the presence of Ag particles with the average size of 12.1 ± 6.5 nm. The HRTEM result reveals that Ag particles are deposited on the surface and inside the lumen of HNT, which is in-line with slight decrease in SBET attributed to some pore blocking in Ag-HNTSA/T. The catalytic activity of the fabricated Ag-HNTX/T (X = SA, OX or SB) was evaluated through the borohydride-assisted degradation of organic contaminants, i.e. methyl orange (MO), methylene blue (MB), p-nitrophenol (p-NP), and bromocresol green (BG). The Ag-HNTX/T catalyst exhibited excellent catalytic activity and the process follows the pseudo-first order kinetics. The Ag-HNTX/T possesses sustainable catalytic performance up to 15 recycled applications.

A practical and direct method was developed for the production of versatile alkyl boronate esters via transition metal-free borylation of primary and secondary alkyl sulfones. The key to the success of the strategy is the use of bis(neopentyl glycolato) diboron (B2neop2), with a stoichiometric amount of base as a promoter. The practicality and industrial potential of this protocol are highlighted by its wide functional group tolerance, the late-stage modification of complex compounds, no need for further transesterification, and operational simplicity. Radical clock, radical trap experiments, and EPR studies were conducted which show that the borylation process involves radical intermediates.
