We have developed a Keggin polyoxometalate (POM)-based ionic-liquid (IL)-immobilizing rhodium single-atom Rh catalyst (MTOA)₅[SiW₁₁O₃₉Rh] (MOTA=methyltrioctylammonium cation) that can afford exceptionally high catalytic activity for the hydroformylation of alkenes to produce aldehydes at an ultralow loading of Rh (ca. 3 ppm). For styrene hydroformylation, both the conversion and the yield of the aldehyde can reach almost 99 %, and a TOF as high as 9000 h^-1 was obtained without using any phosphine ligand in the reaction process. Further characterization by FTIR, ICP and ESI-MS anal. revealed that the single Rh atom was incorporated in the lacunary POM anions. In particular, the bulky IL cation can play an addnl. role in stabilizing Rh species and thus prevent aggregation and leaching of Rh species. The IL catalyst was miscible with n-hexane at temperatures; this contributed to exceptionally high activity for hydroformylation even at ultra-low loading of IL catalyst. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Related Products of 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Related Products of 5137-55-3

Precisely deposited Pd on ZnO (002) facets derived from complex reduction strategy for methanol steam reforming was written by Chen, Yue;Dai, Qiguang;Zhang, Qiyao;Huang, Yongmin. And the article was included in International Journal of Hydrogen Energy in 2022.Name: Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

Pd/ZnO catalysts are promising for onboard hydrogen production through methanol steam reforming (MSR), but their selectivity still requires improving. In this research, a flower-like spherical ZnO material with mainly exposed (002) facet was prepared through surfactant-assisted hydrothermal method. The surfactant tartaric groups also serve as coordinating groups to adsorb Pd²⁺ to form a complex, which is further reduced to metallic Pd. By virtue of preferential adsorption of the surfactant on (002) facet, Pd particles are confined to (002) facet. The calcined PdO-ZnO-T-X catalyst shows highly dispersed PdO nanoparticles. Characterization results suggest that strong interaction between ZnO (002) facet and small PdO particles can facilitate complete PdO reduction and PdZn formation, and can effectively retard PdZn decomposition under oxidizing atm. This research discloses structure-performance relationship of Pd/ZnO catalysts and provides a novel strategy for further improving their MSR performance. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Name: Sodium tetrachloropalladate(II)).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Name: Sodium tetrachloropalladate(II)

And the article was included in Anti-Cancer Agents in Medicinal Chemistry in 2016.Computed Properties of C9H6Cl2N4 The following contents are mentioned in the article:

Dual action alkyl(aryl)amino-1,3,5-triazines functionalized with nitrogen mustards were obtained by treating 2-alkyl(aryl) amino-4-chloro-6-methoxy-1,3,5-triazines with amines or amino acid Me esters, followed by reactions with 1,4-diazabicyclo[2.2.2]octane (DABCO) and rearrangement with an opening diazabicyclic fragment, leading to the formation of 2-chloroethylamino moiety. In vitro antitumor activity was tested in the standard human breast cancer MCF-7 and MDA-MB-231 cell lines using flow cytometry, based on the detection of apoptosis through qual. anal. of morphol. changes, DNA fragmentation, DNA loss and membrane changes. For all the compounds studied, induced apoptosis was substantially stronger than necrosis at concentrations of both 5 μM and 50 μM, and in some cases there was no increase in necrotic cell death for the estrogen dependent MCF-7 cell line. The most active compounds were derivatives of triazine substituted with phenylamine (IC50 = 12.30 μM) and/or p-tolylamine fragments (IC50 = 7.40 μM).

And the article was included in Nature Communications in 2022.Application In Synthesis of Lithium chloride The following contents are mentioned in the article:

Sorption-based atm. water harvesting has the potential to realize water production anytime, anywhere, but reaching a hundred-gram high water yield in semi-arid climates is still challenging, although state-of-the-art sorbents have been used. Here, we report a portable and modularized water harvester with scalable, low-cost, and lightweight LiCl-based hygroscopic composite (Li-SHC) sorbents. Li-SHC achieves water uptake capacity of 1.18, 1.79, and 2.93 g g^-1 at 15%, 30%, and 60% RH, resp. Importantly, considering the large mismatch between water capture and release rates, a rationally designed batch processing mode is proposed to pursue maximum water yield in a single diurnal cycle. Together with the advanced thermal design, the water harvester shows an exceptional water yield of 311.69 g day-1 and 1.09 g gsorbent-1 day-1 in the semi-arid climate with the extremely low RH of ∼15%, demonstrating the adaptability and possibility of achieving large-scale and reliable water production in real scenarios. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Application In Synthesis of Lithium chloride).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.

Electrochemistry of Ferrocene-Functionalized Phosphonium Ionic Liquids was written by Weaver, Joshua E. F.;Breadner, Daniel;Deng, Fanguo;Ramjee, Bala;Ragogna, Paul J.;Murray, Royce W.. And the article was included in Journal of Physical Chemistry C in 2011.Synthetic Route of C6H12BrCl The following contents are mentioned in the article:

The synthesis of and voltammetry in undiluted form of several ferrocene-functionalized phosphonium ionic liquids is reported. Electron transport in the mixed valent diffusion layer around an electrode occurs primarily by Fc^+/0 electron self-exchange reactions, as opposed to phys. diffusion of the ferrocenated phosphonium species. The apparent diffusion coefficients for electron transport and for the counterions of the ionic liquid, and in particular their activation energy barriers, are similar to one another, evidence for the control of rates of electron transport by relaxation of the counterion atm. For a net transport of electronic charge to accompany electron transfer, counterion displacement must occur to relax the charge displacement associated with the electron transfer. The ferrocenated phosphonium ionic liquids thus behave in a manner like that of previously studied redox ionic liquids based on combinations of redox groupings with imidazolium and with short-chain polyether functionalities. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Synthetic Route of C6H12BrCl).

Azo-PROTAC: Novel Light-Controlled Small-Molecule Tool for Protein Knockdown was written by Jin, Yu-Hui;Lu, Meng-Chen;Wang, Yan;Shan, Wen-Xin;Wang, Xuan-Yu;You, Qi-Dong;Jiang, Zheng-Yu. And the article was included in Journal of Medicinal Chemistry in 2020.Computed Properties of C6H12BrCl The following contents are mentioned in the article:

Reversibly altering endogenous protein levels are persistent issues. Herein, we designed photoswitchable azobenzene-proteolysis targeting chimeras (Azo-PROTACs) by including azobenzene moieties between ligands for the E3 ligase and the protein of interest. Azo-PROTACs are light-controlled small-mol. tools for protein knockdown in cells. The light-induced configuration change can switch the active state to induce protein degradation activity, which can be reversely controlled by light exposure in intact cells. We compared the protein degradation abilities of Azo-PROTACs with different configurations and linker lengths. Using the stable form with the best degradation ability against the BCR-ABL fusion and ABL proteins in myelogenous leukemia K562 cells, we showed that Azo-PROTAC combines the potent protein knockdown and facile cell uptake properties of the small-mol. PROTAC with a reversible photoswitchability, offering a promising chem. knockdown strategy based on the light-induced reversible on/off properties.

By leveraging easily accessible tert-Bu isocyanide as the CO surrogate, a nickel-catalyzed allylic carbonylative coupling with alkyl zinc reagent RZnX (R = Me, n-Bu, Bn, cyclopentyl, 2-chloropyridin-5-yl, etc.; X = Br, Cl), allowing for the practical and straightforward preparation of synthetically important β,γ-unsaturated ketones R¹CH=C(R²)CH(R³)C(O)R (R¹ = n-Pr, Ph, cyclohexyl, furan-2-yl, etc.; R² = H, Me; R³ = H, Me, Et, cyclopropyl) in a linear-selective fashion with excellent trans-selectivity under mild conditions was described. Moreover, the undesired polycarbonylation process which is often encountered in palladium chem. could be completely suppressed. This nickel-based method features excellent functional group tolerance, even including the active aryl iodide functionality to allow the orthogonal derivatization of β,γ-unsaturated ketones.

And the article was included in Environmental Science and Pollution Research in 2022.Reference of 13820-53-6 The following contents are mentioned in the article:

NiFe-layered double hydroxide (NiFe-LDH)-loaded ultrafine Pd nanocatalysts (Pd/NiFe-LDHs) were prepared by a facile ultrasonic-assisted in situ reduction technol. without any stabilizing agents or reducing agents. Pd/NiFe-LDHs were characterized by FT-IR, XRD, XPS, and TEM. PdNPs are uniformly dispersed on NiFe-LDHs with a particle size distribution of 0.77-2.06 nm and an average particle size of 1.43 nm. Hydroxyl groups in Fe-OH and Ni-OH were dissociated into hydrogen radicals (·H) excited by ultrasound, and ·H reduced Pd²⁺ to ultrafine PdNPs. Then, Pd was coordinated with O in Ni-O and Fe-O, which improved the stability of the catalysts. Pd/NiFe-LDHs completely degraded 4-NP in 5 min, and the TOF value was 597.66 h^-1, which was 16.7 times that of com. Pd/C. The 4-NP conversion rate remained at 98.75% over Pd/NiFe-LDHs after 10 consecutive catalytic cycles.
