The reactions of Zn(OAc)2·2H2O with various positional isomers of lutidine were explored with a view to understand the factors responsible for the nuclearity/aggregation and acetate coordination modes of the products. The reactions of Zn(OAc)2-2H2O with 3,5-lutldine, 2,3-lutidlne, 2,4-lutidine, and 3,4-lutidine in a 1:1 ratio in methanol at ambient temperature afforded three discrete trlnuclear complexes [Zn 3(OAc)2(mu2-eta2: eta1-OAc)2(mu2 eta1 :eta1-OAc)2(H2O)2(3,5lutidine) 2] (1), [Zn3(mu2-eta1 :eta1-OAC)4(mu2-eta2: eta0-OAC)2L2] [L = 2,3-lutidine (2) and 2,4-lutidine (3)], and a onedimensional coordination polymer [Zn(OAc)(mu2 eta1:eta1-OAc)(3,4-lutidine) ] (4) in 93, 79, 81, and 94% yields, respectively. Complexes 1-4 were characterized by microanalytical, IR, solution (1H and 13C), and solid-state cross-polarization magic angle spinning 13C NMR spectroscopic techniques and single-crystal X-ray diffraction data. Complex 1 is unique In that it contains three types of acetate coordination modes, namely, monodentate, bridging bidentate, and asymmetric chelating bridging. Variable-temperature 1H NMR data indicated that complex 1 partially dissociates In solution, and the remaining undissociated 1 undergoes a rapid “carboxylate shift” even at 218 K. The plausible mechanism of formation of complexes 1 -4 was explained with the aid of a point zero charge (pzc) model, according to which the nuclearity/aggregation observed In complexes 1-4 depends upon the number and nature of equilibrating species formed upon dissolution of the reactants In methanol, and these In turn depend upon the subtle basic/steric properties of lutidines. Further, noncovalent Interactions play a crucial role In determining the nuclearity/ aggregation and acetate coordination modes of the products.

A fluoro derivative can be produced by reacting a hydroxy derivative with sulfuryl fluoride (SO2F2) in the presence of an organic base or in the presence of an organic base and a salt or complex composed of an organic base and hydrogen fluoride. This process enables to advantageously produce an optically active fluoro derivative (e.g., a 4-fluoroproline derivative, a 2′-deoxy-2′-fluorouridine derivative and an optically active alpha-fluorocarboxylate ester derivative) which is an important intermediate for the production of a pharmaceutical or agricultural agent or an optical material, even in large quantity without using a perfluoroalkanesulfonyl fluoride which is undesirable for industrial applications.

The problem of molecular thermal (Pq) polarization estimation in the substances wiih different forms of aggregation and using different experimental techniques is discussed. It is shown on the base of numerous experimental data analysis that Pq includes both rotational (Prot) and orientauonal (Por) components, which may be commensurable in magnitude in gases and gasiform condensed media. The principle of equal distribution of molecules’ thermal polarization over their kinetic degrees of freedom is being satisfied, so Prot, term should not be neglected. The neglect of this fact on estimation of the molecular dipole moments using the first method of Debye results in ?(5/3) or ?/(4/3) times overestimated dipole moment values.

The Rh(I)-catalyzed direct arylation of azines has been developed. Quinolines and 2-substituted pyridines couple with aryl bromides to efficiently afford ortho-arylated azine products using the commercially available and air-stable catalyst [RhCl(CO)2]2. Electron-deficient and electron-rich aromatic bromides couple in good yields, and hydroxyl, chloro, fluoro, trifluoromethyl, ether, and ketone functionalities are compatible with the reaction conditions. Aroyl chlorides also serve as effective azine coupling partners to give ortho-arylation products via a decarbonylation pathway.

Cyclic and acyclic polyethers have been analysed by atmospheric pressure ion mobility spectrometry (IMS). The reduced mobilities of gas-phase cyclic polyether ions may be distinguished from their acyclic analogues as a consequence of differences in the collision cross-sections of their adopted conformations. Peaks attributed to polyether/protonated amine complexes are formed when polyethers are introduced in the presence of N-ethylmethylamine, n-propylamine and benzylamine vapour. Variations in the reduced mobilities for the polyether complexes containing isomeric N-ethylmethylamine and n-propylamine guests are associated with small conformational differences for these ions. SYBYL molecular modelling software was used to confirm structural characteristics inferred from the experimental mobility data.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

Linear free energy relationships have been established in the formation of hydrogen-bonded complexes of various OH reference acids with a wide variety of proton acceptors. The effects of temperature, solvent, and substituents have been examined. A unique base parameter, pKHB, has been defined which measures the relative strength of the acceptor in hydrogen-bonded complex formation with any suitable OH reference acid. pKHB values do not correlate with aqueous pKA values, except within series having a common functional center and variable electronic effects of substituents. pKHB values also are not applicable to reference acids involving internal hydrogen bonding and are presumably not applicable to systems in which there is substantial formation of the hydrogen-bonded ion pair (in mobile equilibrium with the hydrogen-bonded complex). Evidence is presented that the pKHB scale is applicable (at least qualitatively) to other relatively weak interactions between bases and a shielded center of positive charge. The highly dispersed family relationships between pKHB and corresponding pKA values are indicated to be useful in distinguishing the atomic center of complexing in polyfunctional bases.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 108-47-4 is helpful to your research. 108-47-4

Electron-deficient nitrogen-containing heteroaromatics, such as quinoline, isoquinoline, and pyridine, were treated with benzoyl peroxide in dioxane, tetrahydropyran, tetrahydrofuran, diethyl ether, and dipropyl ether at 80C to form alkylated nitrogen-containing heteroaromatics in good yields under transition-metal-free conditions. This method was successfully applied to the preparation of lariat aza-crown ethers using 18-crown-6 or 15-crown-5 with quinoline and isoquinoline in the presence of benzoyl peroxide in good yields under irradiation conditions with a Hg lamp.

Application In Synthesis of 2,4-Dimethylpyridine

A facile and general Br°nsted acid-catalyzed deuteration at the methyl group of N-heteroarylmethanes was achieved through a dearomatic enamine intermediate under relatively mild reaction conditions. Both 2-methyl and 4-methyl groups in quinolines were deuterated with high deuterium incorporation. Pyridines, benzo[d]thiazoles, indoles and imines including these clinical drugs were also deuterated efficiently at the methyl groups. This reaction could be conducted on a large scale (500 mmol), showing its good potential for use in large-scale synthesis.
