Dehydrated Xilinhaote lignite (XL) and Huolinguole lignite (HL) were depolymerized in supercritical methanol at 310 C and the resulting soluble reaction mixtures were analyzed with GC/MS. The results show that the GC/MS-detectable species can be classified into hydroxybenzenes (HBs), esters, ketones, alkanols, arenes, methoxybenzene, alkanes, alkenes, nitrogen-containing organic compounds, sulfur-containing organic compounds, aldehydes and other compounds. However, the difference in the product yield from different coals is significant. The most abundant products are HBs from XL and esters from HL.

A fast and accurate lipophilicity determination is fundamental in the drug discovery process, as long as it is a relevant property in the absorption, distribution, metabolism, excretion and toxicity (ADMET) of a potential drug substance. In the present work, different models based on chromatographic retention values for a large set of compounds and some of their molecular descriptors (calculated by ACD/Labs or CODESSA programs) have been examined in order to establish reliable equations for log Po/w determination from fast chromatographic hydrophobicity index (CHI) measurements. This appears to be a very interesting high-throughput methodology for screening purposes, since CHI values can be measured by UHPLC in very short runs (<4 min) and molecular descriptors can be easily computed from the structure of any compound. The selected final descriptors were Abraham's hydrogen-bond acidity (A) and excess molar refraction (E) from ACD/Labs, and hydrogen-bond acidity HDCA-1/TMSA and HOMO-LUMO polarizability descriptors from CODESSA software. The proposed equations allow an accurate determination of log Po/w with standard errors in the range of 0.4 units. The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research.SDS of cas: 108-47-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108-47-4, in my other articles.

A series of complexes with general formula M(Xan)2L2 (M = Ni(II), Xan = O-amyldithiocarbonato, L = 3-methylpyridine, 2,4-; 3,4-; 3,5-dimethylpyridines and 2,4,6-trimethylpyridine) have been synthesized and characterized by elemental analysis and various physico-chemical techniques such as magnetic susceptibility measurements, conductivity measurements, UV-Visible, Infrared spectral data. On the basis of electronic spectra and magnetic susceptibility measurements, an octahedral geometry has been proposed for all the complexes. IRspectral data shows that the substituted pyridines in all these complexes coordinate to the metal ion through nitrogen atoms occupying fifth and sixth axial positions where as O-alkyldithiocarbonate act as monoanion bidentate ligand and occupy the planar positions of octahedral structures. The X-ray diffraction analysis of one of the adducts bis(O-amyldithiocarbonato) bis(3,5-dimethylpyridine) nickel(II) is also investigated. The complex crystallizes in the monoclinic space group P21/c with unit cell parameters a = 9.167(2) A, b = 18.255(4) A, c = 9.299(2) A and beta = 103.47(2). The dihedral angle between dithio-groups and the pyridine ring is 88.9(1). The crystal structure of the molecule is stabilized by pi-pi interactions. Springer Science+Business Media New York 2012.

ConspectusNickel complexes exhibit distinct properties from other group 10 metals, including a small nuclear radius, high paring energy, low electronegativity, and low redox potentials. These properties enable Ni catalysts to accommodate and stabilize paramagnetic intermediates, access radical pathways, and undergo slow beta-H elimination. Our research program investigates how each of these fundamental attributes impact the catalytic properties of Ni, in particular in the context of alkene functionalization.Alkenes are versatile functional groups, but stereoselective carbofunctionalization reactions of alkenes have been underdeveloped. This challenge may derive from the difficulty of controlling selectivity via traditional two-electron migratory insertion pathways. Ni catalysts could lead to different stereodetermining steps via radical mechanisms, allowing access to molecular scaffolds that are otherwise difficult to prepare. For example, an asymmetric alkene diarylation reaction developed by our group relies upon the radical properties of Ni(III) intermediates to control the enantioselectivity and give access to a library of chiral alpha,alpha,beta-triarylethane molecules with biological activity.Mechanistic studies on a two-component reductive 1,2-difunctionalization reaction have shed light on the origin of the cross-electrophile selectivity, as C sp2 and C sp3 electrophiles are independently activated at Ni(I) via two-electron and radical pathways, respectively. Catalyst reduction has been identified to be the turnover-limiting step in this system. A closer investigation of the radical formation step using a (Xantphos)Ni(I)Ar model complex reveals that Ni(I) initiates radical formation via a concerted halogen-abstraction pathway.The low redox potentials of Ni have allowed us to develop a reductive, trans-selective diene cyclization, wherein a classic two-electron mechanism operates on a Ni(I)/Ni(III) platform, accounting for the chemo- and stereoselectivity. This reaction has found applications in the efficient synthesis of pharmaceutically relevant molecules, such as 3,4-dimethylgababutin.The tendency of Ni to undergo one-electron redox processes prompted us to explore dinuclear Ni-mediated bond formations. These studies provide insight into Ni-Ni bonding and how two metal centers react cooperatively to promote C-C, C-X, and N-N bond forming reductive elimination.Finally, isolation of beta-agostic Ni and Pd complexes has allowed for X-ray and neutron diffraction characterization of these highly reactive molecules. The bonding parameters serve as unambiguous evidence for beta-agostic interactions and help rationalize the slower beta-H elimination at Ni relative to Pd. Overall, our research has elucidated the fundamental properties of Ni complexes in several contexts. Greater mechanistic understanding facilitates catalyst design and helps rationalize the reactivity and selectivity in Ni-catalyzed alkene functionalization reactions.

The aryne [3 + 2] cycloaddition process with pyridinium imides breaks the aromaticity of the pyridine ring. By equipping the imide nitrogen with a sulfonyl group, the intermediate readily eliminates a sulfinate anion to restore the aromaticity, leading to the formation of pyrido[1,2-b]indazoles. The scope and limitation of this reaction are discussed. As an extension of this chemistry, N-tosylisoquinolinium imides, generated in situ from N?-(2-alkynylbenzylidene)-tosylhydrazides via an AgOTf-catalyzed 6-endo-dig electrophilic cyclization, readily undergo aryne [3 + 2] cycloaddition to afford indazolo[3,2-a]-isoquinolines in the same pot, offering a highly efficient route to these potential anticancer agents.

Abstract: The reaction of cobalt(II) chloride with potassium myrtenate (KMyr) followed by addition of 2,3-lutidine in ethanol gives the trinuclear compound [Co3(Myr)6(2,4-Lut)2] (I). The central cobalt(II) atom is linked to each of the two other metal atoms by three myrtenic acid anions. The reaction of a solution of compound I with lithium myrtenate (LiMyr) results in the formation of tetranuclear heterometallic complex [Li2-Co2(Myr)6(2,4-Lut)2] (II). Compound II is composed of two binuclear {LiCo(Myr)3(2,4-Lut)} moieties, in which the lithium(I) atoms are linked to cobalt(II) atoms by bridging myrtenate anions. The lithium atoms are connected by two oxygen atoms of acid anions. Compounds I and II were characterized by X-ray diffraction (CIF files CCDC nos. 1898096 (I), 1898097 (II)).

Pyridine, its N-oxide, and their derivatives are exciting classes of organic bases. These compounds show widespread biological activity, and they are often used in synthesis. In this work results on theoretical calculations of acid dissociation constants as pKa of pyridine, its N-oxide, and their derivatives were done based on the thermodynamic cycle in water and acetonitrile. Additionally, gas-phase basicity (GB) and proton affinity (PA) values were computed for systems studied. All pKa values were obtained using B3LYP, M06-2X, and G4MP2 methods in the gas phase, which were combined with the PCM model calculations (at the Hartree-Fock method) and with the use of four different scale factors alpha. Theoretical GB, PA, and pKa values were then compared with the available experimental ones. Results obtained from B3LYP and M06-2X methods are quite similar and compatible with experimental ones in terms of quality with correlation coefficients values R2 higher than 0.9, whereas results received from G4MP2 deviate strongly. The calculated pKa values are highly sensitive to the scale factors alpha used in the computational procedure. Root-mean-square deviations (RMSD) between both theoretically and experimentally available pKa values of systems studied were also computed. The RMSD values are lower than 0.8 for the best results, suggesting that the theoretical model presented in this work is promising for applications for pKa calculations of different classes of compounds.

Abstract Carbonylation of aromatic amines by direct insertion of carbon monoxide is catalyzed by PdCl2(XnPy)2 complexes (where Py = pyridine, X = -CH3, -Cl; n = 0-2) and gives, depending on the conditions, ethyl N-phenylcarbamates or N,N?-diphenylureas. For carbonylation of aniline, a proper choice of XnPy ligands in PdCl2(XnPy)2 catalyst and application of molecular oxygen instead of nitrobenzene (conventionally used oxidant for carbonylations) allow to carry out the process under mild conditions with high yield and selectivity. The best results (75% yield of the main product with selectivity of catalyst above 90%) were obtained for the process catalyzed by PdCl2(2,4-Cl2Py)2 complex at 100C and they were greatly improved in comparison to 41% yield and 68% selectivity obtained for CO/nitrobenzene used at 180C.
