Compound: Nickel(II) chloride ethylene glycol dimethyl ether complex, is researched, Molecular C4H10Cl2NiO2, CAS is 29046-78-4, about Evidence for Photocatalyst Involvement in Oxidative Additions of Nickel-Catalyzed Carboxylate O-Arylations. Author is Malik, Jamal A.; Madani, Amiera; Pieber, Bartholomaeus; Seeberger, Peter H..

Dual photocatalysis and nickel catalysis can effect cross-coupling under mild conditions, but little is known about the in situ kinetics of this class of reactions. We report a comprehensive kinetic examination of a model carboxylate O-arylation, comparing a state-of-the-art homogeneous photocatalyst (Ir(ppy)3) with a competitive heterogeneous photocatalyst (graphitic carbon nitride). Exptl. conditions were adjusted such that the nickel catalytic cycle is saturated with excited photocatalyst. This approach was designed to remove the role of the photocatalyst, by which only the intrinsic behaviors of the nickel catalytic cycles are observed The two reactions did not display identical kinetics. Ir(ppy)3 deactivates the nickel catalytic cycle and creates more dehalogenated side product. Kinetic data for the reaction using Ir(ppy)3 supports a turnover-limiting reductive elimination. Graphitic carbon nitride gave higher selectivity, even at high photocatalyst-to-nickel ratios. The heterogeneous reaction also showed a rate dependence on aryl halide, indicating that oxidative addition plays a role in rate determination The results argue against the current mechanistic hypothesis, which states that the photocatalyst is only involved to trigger reductive elimination.

Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, is researched, Molecular C12H9N3, CAS is 2208-59-5, about Influence of the molecular structure on the inhibitor properties of benzimidazole derivatives on mild steel corrosion in 1 M hydrochloric acid. Author is Popova, A.; Christov, M.; Deligeorgiev, T..

Six benzimidazole derivatives were investigated as corrosion inhibitors for mild steel in 1 M HCl by using gravimetric and polarization techniques. The inhibitor efficiency depended on the concentration and on structure of the mols. The results were interpreted by using an adsorption model based on inhibitor adsorption in the form of non-protonated and protonated mols. Five of the six examined compounds adsorbed according to the Frumkin adsorption isotherm. An attempt was made to find a correlation between the inhibition efficiency and some parameters of the electronic structure of the mol., like induction and resonance effects of the substituents and ionization potential. A correlation also was attempted between the inhibition efficiency and some parameters of the chem. structure of the mol., like the mol. area and others. No simple correlation was found.

Author is Hattori, Shingo; Hirata, Shuntaro; Shinozaki, Kazuteru.

We found emission intensity enhancement for fac-Ir(ppy)3 (ppy = 2-(2′-phenyl)pyridine) in aerated DMSO during photoirradiation for the first time. This phenomenon was concluded to be responsible for the consumption of 3O2 dissolved in DMSO through di-Me sulfone production by photosensitized reaction using fac-Ir(ppy)3. A 3O2 adduct of DMSO mol. was detected by UV absorption measurement and theor. calculation We proposed a mechanism for the emission enhancement reaction including 1,3O2 mols. and 1,3O2-DMSO adducts and validated it through a simulation of emission intensity change using an ordinary differential equation solver.

From this literature《Catalytic asymmetric heterogeneous aziridination of styrene using CuHY: effect of nitrene donor on enantioselectivity》,we know some information about this compound(132098-59-0)Computed Properties of C19H18N2O2, but this is not all information, there are many literatures related to this compound(132098-59-0).

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Bis((S)-4-phenyl-4,5-dihydrooxazol-2-yl)methane(SMILESS: C1(CC2=N[C@@H](C3=CC=CC=C3)CO2)=N[C@@H](C4=CC=CC=C4)CO1,cas:132098-59-0) is researched.Product Details of 676-96-0.

Let’s take a look at the latest research on this compound (cas:132098-59-0).

The copper-catalyzed aziridination of styrene with copper-exchanged zeolite Y (CuHY) and copper(II) triflate as catalysts is described in detail. Two nitrene donors, [N-(p-tolylsulfonyl)imino]phenyliodinane (PhI:NTs) and [N-(p-nitrophenylsulfonyl)imino]phenyliodinane (PhI:NNs) are compared. Modification of the CuHY catalyst with nonracemic bis(oxazolines) affords enantioselective heterogeneous catalysts; a range of chiral bis(oxazolines) were studied. The ratio of nitrene donor to styrene is shown to be an important factor controlling both the yield and ee of aziridine formed. The best results are obtained with PhI:NNs; ee, ≥ 90%, together with high yields (≥ 85%), can readily be achieved with this nitrene donor using acetonitrile as solvent. Addition of the nitrene donor over a period of time, rather than all at the start of the reaction, is shown to enhance the yield of the aziridine but to decrease the enantiomeric excess of the aziridine for both homogeneous and heterogeneous catalysts. Experiments in which the breakdown products of the nitrene donor, iodobenzene and the corresponding sulfonamide, are added at the start of the reaction show that a complex interplay exists at the copper active site between the reactants, products, chiral modifier and the solvent. The heterogeneous catalyst, CuHY, is found to give enhanced enantioselection for a range of bis(oxazolines) compared to the homogeneous catalyst; the effect is due to the confinement of the catalyst within the micropores of the zeolite.

Author is Yue, Huifeng; Zhu, Chen; Kancherla, Rajesh; Liu, Fangying; Rueping, Magnus.

Alkynes are an important class of organic mols. due to their utility as versatile building blocks in synthesis. Although efforts have been devoted to the difunctionalization of alkynes, general and practical strategies for the direct hydroalkylation and alkylarylation of terminal alkynes under mild reaction conditions are less explored. Herein, a photoredox/nickel dual-catalyzed anti-Markovnikov-type hydroalkylation of terminal alkynes as well as a one-pot arylalkylation of alkynes with alkyl carboxylic acids and aryl bromides via a three-component cross-coupling has been discussed. The results indicate that the transformations proceed via a new mechanism involving a single-electron transfer with subsequent energy-transfer activation pathways. Moreover, steady-state and time-resolved fluorescence-spectroscopy measurements, d. functional theory (DFT) calculations, and wavefunction anal. have been performed to give an insight into the catalytic cycle.

Author is Naweephattana, Phiphob; Sawatlon, Boodsarin; Surawatanawong, Panida.

The hydroheteroarylation of allylbenzene with pyridine as catalyzed by Ni/AlMe3 and a N-heterocyclic carbene ligand has recently been established. D. functional calculations revealed that the common stepwise pathway, which involves the C-H oxidative addition of pyridine-AlMe3 before the migratory insertion of allylbenzene, is unlikely as the migratory insertion needs to overcome a prohibitively high energy barrier. In contrast, the ligand-to-ligand hydrogen transfer pathway is more favorable in which the hydrogen is transferred directly from the para-position of pyridine-AlMe3 to C2 of allylbenzene. Our distortion-interaction anal. and natural bond orbital anal. indicate that the interaction energy is strongly correlated with the extent of the charge transfer from the alkene (hydrogen acceptor) to the pyridine-AlMe3 (hydrogen donor), which dictates the selectivity of the H-transfer to the C2 position of allylbenzene. Then, the subsequent C-C reductive elimination of the regioselective linear product is facilitated by the steric hindrance of the IPr ligand. Understanding these key factors affecting the product regioselectivity is important to the development of catalysts for hydroheteroarylation of alkenes.
