A number of chiral chelating conjugates combining a bispidine central backbone and one or two pinene side fragments were synthesized. It was shown for the first time that the synthesized compounds are capable to act as catalysts in the Henry reaction both individually and in the presence of metal salts. It was found that the best catalytic results were shown for bis-tertiary amine combining bispidinone and two (-)-myrtenol fragments, and copper as well as zinc acetates.

Hybrid catalysts consisting of alkaline earth iodides (AeI(2)) and the Schwesinger base(tBu)P4 catalyse the intramolecular alkene hydroamination of H2C=CHCH2CR2CH2NH2[CR2=CPh2, C(CH2)(5), CMe2]. Activities decrease along the row: Ca > Sr >> Mg > Ba. Hybrid catalysts consisting of(tBu)P4 and ZnI2, AlI3, FeCI(3)or NaI were found to be fully inactive. Also, the hybrid catalyst(tBu)P3/CaI(2)was not active which means that the base strength of the non-nucleophilic organic base must be higher than that of(tBu)P3 (pK(a)BH(+)= 38.6). Combinations of(tBu)P4 with CaX2(X = Cl, Br, OiPr, OTf, NTf2) were found to be fully inactive which may in part be explained by poor solubility. The hybrid catalysis method is therefore limited to the combination(tBu)P4/CaI(2)but the iodide ligands may be partially or fully replaced by chiral ligands. Chiral modifications of the hybrid catalysts gave in intramolecular alkene hydroaminationeevalues up to 33 %.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7512-17-6, in my other articles.

Electrochemical water splitting is considered as a promising approach to storing renewable electricity in the form of hydrogen fuel. In this work, we report the design and electrocatalytic properties of chiral CuO@Ni with three dimensional (3D) continuous macroporous framework. With the chiral CuO@Ni as anode, the OER overpotential required to achieve the current density of 10 mA/cm(2) was as low as 110 mV in 0.1 M KOH electrolyte, and the hydrogen production rate of water splitting reaction could reach 1070 nL/s. Moreover, the OER overpotential could be regulated easily by controlling the deposition time of chiral CuO layer on Ni. The high catalytic activity of chiral CuO@Ni for water splitting is closely associated with the Chiral-induced spin selectivity (CISS) effect, the large reactive area provided by its 3D macroporous structure, and the effective cooperation between chiral CuO and Ni foam that facilitated the transportation of spin aligned electrons from chiral CuO layer to Ni. The results shown in this work indicate a simple and promising strategy to improve the electrocatalytic activity of other chiral earth-abundant catalysts for water splitting.

We herein report the well-defined two novel chiral palladium(II) complexes 1 (b-c), of the chiral N-fused tricyclic triazolooxazine derived mesoionic carbene (tz-MIC) ligand 1a . The chiral tricyclic PEPPSI type complex (pyridine enhanced pre-catalyst preparation stabilization and initiation) namely, trans-[tzMIC)-PdI2(pyridine)] (1b ), and the chiral tricyclic bis(tz-MIC)-palladium complex namely, cis-[tz-MIC)(2)PdCl2] (1c ). The chiral tricyclic trans-[tz-MIC)-PdI2(pyridine)] PEPPSI type complex (pyridine enhanced pre-catalyst preparation stabilization and initiation) (1b ) was directly obtained from their respective chiral tricyclic triazolooxazinium iodide salt (1a ), by treatment with PdCl2 and K2CO3 in pyridine in 77% yield. The chiral tricyclic triazolooxazinium iodide salt (1a ), was first converted to its in-situ silver analogue by reaction with Ag2O and then subsequently upon treatment with (COD)PdCl2 to produce the chiral tricyclic (tz-MIC)(2)PdCl2 type palladium complex (1c ) in 84% yield. All these palladium complexes were isolated for the first time and structurally characterized by (1) H NMR and C-13{H-1}-NMR spectroscopy, FT-IR spectroscopy, mass spectrometry, elemental analysis and single crystal X-ray crystallography.

A chiral phosphoric acid-catalyzed asymmetric 1,4-addition of benzofuran-derived azadienes with 3-substituted indoles has been established, which offered enantioenriched tri(hetero)arylmethane products in generally good yields (up to 98 %) and high enantioselectivities (up to 99 : 1 er). This reaction has not only realized the application of chiral phosphoric acid as a competent catalyst in the asymmetric transformations of benzofuran-derived azadienes, but also has accomplished the task of developing chiral Bronsted acid-catalyzed asymmetric 1,4-additions of benzofuran-derived azadienes, which will enrich the research contents of chiral phosphoric acid catalysis and the chemistry of benzofuran-derived azadienes.

A copper-catalyzed enantioconvergent Suzuki-Miyaura C(sp(3))-C(sp(2)) cross-coupling of various racemic alkyl halides with organoboronate esters has been established in high enantioselectivity. Critical to the success is the use of a chiral cinchona alkaloid-derived N,N,P-ligand for not only enhancing the reducing capability of copper catalyst to favor a stereoablative radical pathway over a stereospecific S(N)2-type process but also providing an ideal chiral environment to achieve the challenging enantiocontrol over the highly reactive radical species. The reaction has a broad scope with respect to both coupling partners, covering aryl- and heteroarylboronate esters, as well as benzyl-, heterobenzyl-, and propargyl bromides and chlorides with good functional group compatibility. Thus, it provides expedient access toward a range of useful enantioenriched skeletons featuring chiral tertiary benzylic stereocenters.

Asymmetric insertion of an arylvinylcarbenoid into the C-H bond for direct enantioselective C(sp(2))-H functionalization of aniline derivatives catalyzed by a rhodium(I)-diene complex was developed for the first time. The reaction occurred exclusively at the uncommon vinyl terminus site with excellent E selectivity and enantioselectivities, providing various chiral gamma,gamma-gem-diarylsubstituted alpha,beta-unsaturated esters with broad functional group compatibility under simple and mild conditions. It provides a rare example of the asymmetric C-H insertion of arenes with selective vinylogous reactivity. Synthesis applications of this protocol were featured by several versatile product transformations. Systematic DFT calculations were also performed to elucidate the reaction mechanism and origin of the uncommon enantio- and regioselectivity of the Rh(I)-catalyzed C(sp(2))-H functionalization reaction. The measured and computed inverse deuterium kinetic isotope effect supports the C-C bond-formation step as the rate-determining step. Attractive interactions between the chiral ligand and substrates were also proposed to control the enantioselectivity.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 7512-17-6, Name is N-Acetyl-D-glucosamine, molecular formula is C8H15NO6. In an article, author is Chung, Iljun,once mentioned of 7512-17-6, SDS of cas: 7512-17-6.

Heterogeneous enantioselective catalysis is considered a promising strategy for the large-scale production of enantiopure chemicals. In this work, polymer-capped Pt nanocatalysts having a uniform size were synthesized using poly(vinyl pyrrolidone) (PVP) and poly(vinyl alcohol) and supported on gamma-Al2O3. After a facile heat treatment process, their catalytic performance for enantioselective hydrogenation of alpha-keto esters, a structure-sensitive reaction, was investigated. The presence of residual capping agents on the Pt surface often perturbs the adsorption of reacting species and reduces performance in structure-sensitive reactions. However, the 1 wt % PVP-Pt/Al2O3 catalyst exhibited an enhancement in both activity and enantioselectivity compared to a reference Pt/Al2O3 catalyst prepared by wet impregnation. Under optimized reaction conditions, the cinchonidine-modified PVP-Pt/Al2O3 gave an enantiomeric excess of 95% for the enantioselective hydrogenation of methyl pyruvate despite the low Pt loading. We demonstrate that depending on the type of polymers, the residual capping agents can lead to site-selective blockage of the Pt surface, that is, defects or terraces. Quantitative and qualitative analyses also show that the noticeable improvement in enantioselectivity is attributed to the stable adsorption of chiral modifiers on selectively exposed Pt terrace sites. The findings of this work provide a promising strategy to prepare metal nanoparticles having selectively exposed sites and offer insights into the enhancing effect of residual capping agents on the catalytic properties in structure-sensitive reactions.

Asymmetric allylation and vinylation of aldehydes with allyl halides and vinyl halides have been achieved using the chromium(II)-oxazoline catalyst. The catalyst promotes the highly efficient enantioselective Nozaki-Hiyama-Kishi (NHK) allylation of aldehydes using allyl bromide, producing the corresponding homoallylic alcohols in good yields (up to 84%) and a high level of enantioselectivity (up to 98% ee). Meanwhile, the NHK vinylation of aldehydes produce desired allylic alcohols in satisfactory yields (up to 88%) and a high level of enantioselectivity (up to 97% ee). We developed a reliable and milder protocol for preparing chiral homoallylic and allylic alcohols.
