The quinolinylcyclopalladated complexes 3a-b were synthesised in good yields (81% and 77%) by the insertion reaction of the prepared dinuclear palladium complexes [Pd(C,N-2-C9H4N-CHO-3-R-6)Cl(PPh3)]2 [(R = H (2a), R = OMe (2b)] with isonitrile XyNC (Xy = 2,6-Me2C6H3). The cyclopalladated complexes 3a-b were also obtained in low yields (39% and 33.5%) via a one pot oxidative addition reaction of quinoline chloride 1a-b with isonitrile XyNC:Pd(dba)2 (4:1). The reactions of 3a-b with Tl(TfO) (TfO = triflate, CF3SO3) in the presence of H2O or EtOH causes depalladation reactions of the complexes to provide the corresponding organic compounds 4a-b, 5a-b and 6a-b in yields (41%, 27% and 18-19%). The products were characterized by satisfactory elemental analyses and spectral studies (IR, 1H, 13C and 31P NMR). The crystal structures of 2a, 3a and 3b were determined by X-ray diffraction studies.

Chiral N,N-chelates of formula 6-Me-pyridine-2-CH=N-R (1) and R-N=CH- CH=N-R (2) (R = 6-deoxy-alpha-D-glucoside or 6-deoxy-alpha-D-mannoside residue) and their palladium(0) complexes [Pd(N,N-chelate)(olefin)] (I) were prepared. Symmetrical type 2 ligands induced higher enantioselectivity in the coordination of prochiral olefins. The ability of a type 1 chelate to promote a stereoselective process was also assessed, i.e. dimethylfumarate inserted into the Pd-Me bond formed upon methylation of a type I complex with 50% ee. Finally, a water-soluble Pd0 complex was also prepared by deprotecting the alcoholic functions on the sugar residue, and its molecular structure- determined through X-ray diffractometry.

In this work, trisaminomethane?cobalt complex immobilized onto the surface of Fe3O4 magnetic nanoparticles was successfully prepared via a simple and inexpensive procedure. The prepared nanocatalyst was considered a robust and clean nanoreactor catalyst for the oxidation and synthesis of sulfides under green conditions. This ecofriendly heterogeneous catalyst was characterized by Fourier transform infrared spectroscopy, X-ray diffractometry, energy-dispersive X-ray spectroscopy, inductively coupled plasma-atomic emission spectroscopy, thermogravimetric analysis, vibrating sample magnetometry, X-ray mapping, scanning electron microscopy, and transmission electron microscopy techniques. Use of green medium, easy separation and workup, excellent reusability of the nanocatalyst, and short reaction time are some outstanding advantages of this method.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: catalyst-palladium, you can also check out more blogs about14323-43-4

Magnetic properties of pentacoordinate complexes of the type [Co(bzimpy)X2], X = Cl and Br, were investigated in DC and AC modes. The DC data shows sizeable zero-field splitting for these complexes. The AC susceptibility data confirms slow magnetic relaxation at the applied DC field with two relaxation channels. The low-frequency relaxation time is as slow as tauLF ? 0.1-0.3 s for the Cl and Br complexes at T = 1.9 K.

Contemporary catalytic procedures involving alkylpalladium(ii) have enriched the arsenal of synthetic organic chemistry. Those transformations usually rely on internal coordination through “directing groups”, carefully designed to maximize catalytic efficiency and regioselectivity. Herein, we report structural and reactivity studies of a series of internally coordinated monohaptoallylpalladium complexes. These species enable the direct spectroscopic observation and theoretical study of pi-sigma-pi interconversion processes. They further display unusual dynamic behavior which should be of direct relevance to chemistries beyond catalytic allylic alkylation.

Establishment of a general one-pot cascade reaction protocol would dramatically reduce the effort of multistep organic synthesis. We demonstrate that the unique structure of M12L24 self-assembled complexes gives them the potential to serve as catalyst carriers for enabling continuous chemical transformations. A stereoselective cascade reaction (allylic oxidation followed by Diels-Alder cyclization) with two intrinsically incompatible catalysts was demonstrated. Our system is advantageous in terms of availability, scalability, and predictability.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: catalyst-palladium, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 95464-05-4, Name is 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, molecular formula is C35H32Cl4FeP2Pd

The meta-diaminoaryl ferrocenes Fc-NCN-H (3) and Fc-C{triple bond, long}C-NCN-H (5) (Fc = (eta5-C5H5)(eta5-C5 H4)Fe, NCN-H = C6H3(CH2NMe2)2-3, 5) can be used as precursors in the preparation of heterobimetallic transition metal complexes of structural type Fc-NCN-MX (NCN = [C6H2(CH2NMe2)2-2 ,6]-; MX = PdCl (7), PtCl (8), PtI (9)) and Fc-C{triple bond, long}C-NCN-MX (MX = PdCl (11), PdI (12), PtCl (13)), respectively. They are accessible by applying different synthesis procedures, including oxidative addition and metallation-transmetallation processes. Cyclovoltammetric studies show that the ferrocene moieties in 3, 5, 7-9 and 11-13 can reversibly be oxidised. The potential of the Fe(II)/Fe(III) redox couple decreases with increasing electron density at the NCN pincer unit. The use of 8 as a possible (electro)chemical sensor in the detection of SO2 is discussed as well. The solid-state structures of 8 and 13 are reported. The crystals of 8 contain two molecules of 8 in the asymmetric unit. The plane of the C6H2 moiety is with 27.2(3) and 38.2(3) tilted towards the C5H4 entity, while in 13 an angle of 45.9(3) can be found. The d8-electron configured platinum atoms possess a somewhat distorted square-planar surrounding, setup by two Me2NCH2 ortho-substituents, the NCN Cipso carbon atom and the chloride ligand.

Autophagy inducers represent new promising agents for the treatment of a wide range of medical illnesses. However, safe autophagy inducers for clinical applications are lacking. Inhibition of cdc2-like kinase 1 (CLK1) was recently found to efficiently induce autophagy. Unfortunately, most of the known CLK1 inhibitors have unsatisfactory selectivity. Herein, we report the discovery of a series of new CLK1 inhibitors containing the 1H-[1,2,3]triazolo[4,5-c]quinoline scaffold. Among them, compound 25 was the most potent and selective, with an IC50 value of 2 nM against CLK1. The crystal structure of CLK1 complexed with compound 25 was solved, and the potency and kinase selectivity of compound 25 were interpreted. Compound 25 was able to induce autophagy in in vitro assays and displayed significant hepatoprotective effects in the acetaminophen (APAP)-induced liver injury mouse model. Collectively, due to its potency and selectivity, compound 25 could be used as a chemical probe or agent in future mechanism-of-action or autophagy-related disease therapy studies.
