Five host-guest trimesic-acid-based hydrogen-bonds framework compounds with different guests, namely [(TMA)(4)center dot(TMB)(3)] (1), [(TMA)(2)center dot(DMB)(1.5)] (2), [(TMA)(6)center dot(MP)] (3), [(TMA)center dot(EP)] (4) and [(TMA)center dot(PP)] (5) (TMA = trimesic acid, TMB = 1,3,5-trimethoxybenzene, DMB = 1,4-dimethoxybenzene, MP = 4-methoxyphenol, EP = 4-ethoxyphenol and PP = 4-propoxyphenol), were obtained through co-crystallization, and were characterized by elemental analysis, infrared spectroscopy analysis, and thermogravimetric analysis. The trimesic acid molecules comprise a hydrogen bonding six-membered cyclic host network that is found in a two-dimensional arrangement in compounds 1 and 2, and in a nine-fold interpenetrated three-dimensional structure in compound 3. In compounds 4 and 5, the trimesic acid and EP/PP molecules form a hydrogen-bonded six-membered cyclic network, resulting in a one-dimensional chain structure through O-H horizontal ellipsis O hydrogen bonds.

The crystal structures, Hirshfeld surface analysis and PIXEL calculations are reported for (E)-3-(4-methoxyphenyl)-1-(2-hydroxy-5-isoproproxyphenyl)prop-2-en-1-one, 1, and (E)-3-(3-methoxy-4-isopropoxyphenyl)-1-(2-hydroxy-4,6-diisoproproxyphenyl)prop-2-en-1-one, 2. Different sets of C-H…O, C-H…pi, off-set, face-to-face pi…pi and/or C=O…pi intermolecular interactions are displayed by each compound. Due to the bulk of the isoproproxy unit and the consequent steric hindrance in forming aggregates in the solid state, compounds 1 and 2 exhibit larger interplanar angles than do corresponding chalcones with methoxy units. The total stabilization energies of the crystal packing, E-tot distributed as Coulombic (E-coul), polarization (E-pol), dispersion (E-disp), and repulsion (E-rep) have been computed by PIXEL. For compound 1, six motifs (molecule pairs) and for compound 2, with two independent molecules in the asymmetric unit, thirteen motifs are identified by the PIXEL calculations to have energies, -E-tot, above the cut-offvalue of 10 kJ.mol(-1). For each of these motifs, the largest contributor to the E-tot value is the E-disp term, irrespective of the type(s) of interaction(s) connecting the two molecules, if any, in the motifs.

A mesoporous Zn-based 2-amino terephthalate metal organic framework (IRMOF-3) catalyst was prepared using the solvothermal method. The synthesized catalyst was characterized by powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDAX), and Brunauer-Emmett-Teller surface area analysis (BET). It was applied as an effective heterogeneous catalyst for the synthesis of one-pot four-component polyhydroquinoline derivatives via the Hantzsch condensation. The present method offers several advantages over other reported methods such as easy separation, mild reaction condition, and excellent yield of desired product. Furthermore, the catalyst can be reused without loss in activity.

Bronsted acidities of 19 fluorocompounds in the pK(a) range from 3.5 to 10 have been measured in aqueous solution using an approach involving absolute and relative pK(a) measurements with F-19 NMR. F-19 NMR has not been frequently used for determining pK(a) values, but it has a number of advantages, especially when relative values are considered: accurate concentrations not needed, tolerant to impurities, several compounds can be measured simultaneously, several uncertainty sources cancel out.

BACKGROUND Although phenol is a key intermediate in the plastics and polycarbonate industry, it is also a toxic component that requires removal from dilute aqueous streams, potentially by liquid-liquid extraction (LLX). For LLX, cumene is suggested as a solvent as it is already present in processes in the polycarbonate industry. For the recovery of cumene from phenol by distillation, knowledge on vapor-liquid equilibrium (VLE) behavior is important, in combination with how this is affected by other components possibly present as an impurity or explicitly added as a solvent. This was investigated in this work. RESULTS The binary cumene-phenol system shows a tangent pinch in the binary VLE diagram. Addition of a range of impurities and solvents showed that hydrogen bond accepting compounds strongly improve the relative volatility of the mixture, whereas dodecane, not capable of forming hydrogen bonds, has a negative effect on the relative volatility. CONCLUSION Addition of polar components with hydrogen bonding abilities, i.e. ketones or ethers, affected the relative volatility of cumene over phenol the most positively. Combining two types of components results in similar effects, and clear synergistic effects could not be shown based on current VLE measurements. Addition of an apolar component in combination with polar components with hydrogen abilities had only a minor effect on the relative volatility. (c) 2021 The Authors.

A Pd-catalyzed oxa-(4+4)-cycloaddition between 1-azadienes and (2-hydroxymethyl)allyl carbonates is described. Aurone-derived azadienes furnished polycyclic 1,5-oxazocines in good yields. Interestingly, linear azadienes have also been involved and yielded monocyclic heterocycles with complete regioselectivity. DFT calculations were carried out to gain insight on this observation.

We have recently reported a one-pot procedure for glycosyl amides synthesis using selenocarboxylate as traceless reagent. Herein, we present a further application of selenocarboxylate-azide reaction for amide bond formation on a broader range of substrates, including heterocyclic systems and fatty acid. This method proved to be highly efficient for the synthesis of primary and secondary amides, sulfonamides, imides, phosphoramide and also carbamate. (C) 2020 Elsevier Ltd. All rights reserved.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

We find that quantum mechanical calculations using B3LYP/aug-cc-pVTZ model chemistry involving anharmonic correction on simple conjugated organic compounds without rotating moieties provide the dipole moment values and molecular geometries with high accuracy. In the presence of one or two conjugated electron donating or accepting substituents capable of hindered rotation, the calculated dipole moments reproduce the experimental results equally well only in the cases when the experiments were done at the temperatures at which rotation of substituents remains hindered. In order to reproduce the experimental dipole moments determined at higher temperatures, a model assuming free (unhindered) rotation should be applied. In these cases, the contribution of each rotamer is equal and using anharmonic correction is not necessary. The APFD functional produces similar results and the M062X functional yields larger deviations from the experimental data. The other methods, like HF and MP2, are the least accurate with the basis sets usually employed for interpreting the experimental data.
