A new diamine containing hydroxyl and bis-tert-butyl substituted triphenylpyridine units was synthesized and used in the synthesis of polyimides (PIs) via a one-step polymerization. The diamine and PIs were characterized by FTIR and(1)H-NMR. The aggregated structure of PIs was amorphous by wide angle X-ray diffraction test and all of them exhibited excellent solubility in most organic solvents. The bis-tert-butyl and triphenylpyridine units endowed PIs excellent thermal stability with 10% weight loss temperatures in the range 493-525 degrees C and high glass transition temperature in the range 301-344 degrees C, while the existence of hydroxyl groups provided the possibility for further modification of polymer. The PI membranes had excellent mechanical properties with tensile strength in the range 65-93 MPa. The density of PIs was lower with density in the range 1.266-1.289 g/cm(3). It was foreseeable that PIs will greatly promote the applications of heat-resistant and lightweight PI materials in the future.

Herein, the composite of palladium nanoparticles and graphene oxide (CPG) has been synthesized by a facile and very efficient method that provided chemical selectivity and high catalytic activity. The synthesized CPG was characterized by several techniques such as transmission and high-resolution electron microscopy (TEM and HR-TEM), X-ray diffraction (XRD) and Raman spectroscopy, and Photoelectron spectroscopy (XPS). CPG was tested for selective reduction of nitroarenes at room temperature. After the addition of CPG to the reaction media, catalytic performances were depended upon the cooperative effect of hydrogen activation with Pd nanoparticles, where the lack of electrons favors an excellent performance. Nitroarenes can be bound to the energetically preferred adsorption site for the nitro group in electrically enriched graphene oxide. In addition, the Pd nanoparticles transfer electrons to the graphene oxide which increases the functions of metal and carbon support. CPG exhibits both chemoprotective and high catalytic performance for hydrogenation of nitroarenes at room temperature. Aniline derivatives were obtained with high yields under mild conditions and a practical catalytic system was developed by the use of CPG.

Elemental sulfur, as a by-product of petroleum refining, is regarded as a solid waste stored in above-ground deposits due to limited existing applications, meanwhile, mercury contamination is one of the current environmental issues considering its high toxicity to the human, and how to safely dispose of hazardous waste adsorbents is still an unavoidable problem. This study addresses these need by utilizing sulfur for preparation of a polysulfide complex material to capture Hg(II) and convert the Hg(II)-containing spent adsorbent into a catalyst. Initially, the mesoporous silica was prepared and functionalized by using diatomite and APTES, then, an in-situ preparation method was applied to obtain the amine-mesoporous silica/poly(m-aminothiophenol) nanocomposite (MAP), subsequently sulfur was copolymerized with MAP and vinylic-potato starch through inverse vulcanization, forming the sulfur crosslinked polymers composite cp(MAP-S-PS). Many characterizations were employed to determine the physicochemical structure andmorphology of cp(MAP-S-PS). The adsorption study showed the cp(MAP-S-PS) exhibited the theoretical maximum adsorption capacity of 436.68 mg/g, good regeneration performance after 5 cycles and excellent selectivity between Hg(II) ions and common cations. Furthermore, the collected spent adsorbent cp (MAP-S-PS)/Hg(II) was reused as a catalyst for synthesis of acetophenone with 89% yield, and most of phenylacetylene derivatives were also transformed to corresponding acetophenone in good yields.

Benzoylhydrazine based Schiff base-ligated two new copper(II) complexes, [Cu(L-1)(2)] (1) and [Cu(L-2)(2)] (2) were synthesized by the reaction of Cu(CH3COO)(2)center dot H2O with respective Schiff base ligand 1-[(4-nitrophenyl) ethylidene] benzohydrazide (HL1) or 1-[(4-methoxyphenyl)ethylidene]benzohydrazide (HL2). Both complexes were isolated as greenish solid and fully characterized by elemental analysis, FT-IR, EPR, thermo-gravimetric (TG) analysis and Cyclic Voltammetry. The molecular structures of both complexes have also been determined by single crystal X-ray crystallography, which confirmed the co-ordination of Schiff base ligands through N, O donor atoms and distorted square planar geometry around the Cu(II) ion. Both complexes were found to be good homogeneous catalysts for the synthesis of a wide range of substituted thioethers and 5-substituted 1H-tetrazoles in 92% and 93% yield, respectively, at a low catalyst loading (0.5 mol%). The bond angles and distances, as discerned from the DFT calculations, commusurated with the experimental findings. The energy difference between the HOMO and the LUMO, calculated from DFT studies, was found to be 5.645 eV and 6.459 eV for complex 1 and complex 2, respectively. These results are in harmony with the observed higher catalytic activity of complex 1. (c) 2019 Elsevier B.V. All rights reserved.

Hydrothermal carbonization of salep as a domestic biosource was carried out to afford a biochar, BC, with exceptional catalytic activity. BC can be further magnetized by incorporation of magnetic nanoparticles to furnish a magnetic catalyst, BC-Fe, with improved recovery and recyclability for the hydrogenation of nitroarenes in the absence of any precious metal. BC-Fe was also applied as a catalyst support for the immobilization of Pd nanoparticles and development of an efficient, biocompatible and cost-effective catalyst, Pd@BC-Fe, with utility for the oxidation of benzyl alcohols under mild reaction condition in a selective manner to afford corresponding acids in high yields. The study of the recyclability of the catalyst confirmed high recyclability of Pd@BC-Fe.

We demonstrate a method to boost the photocatalysis of titania by constructing a core-shell structure. The crucial technique is to capsulate the titania nanoparticles by a sheath of nitrogen-doped carbon (TiO2@N-AC) with a thickness at 3.5-7.5 nm, which creates an exceptional effect to accelerate the catalytic hydrogenation of substituted nitroarenes with isopropanol as the hydrogen source under ultraviolet or visible-light irradiation. In the catalytic hydrogenation of various nitroarenes with substituted groups of -Cl, -F, -C-C, -C-O, and -C=N, TiO2@N-AC exhibits high conversions and selectivities to the corresponding functionalized anilines, even outperforming the catalysts containing noble metals. Mechanism study demonstrates that the TiO2@N-AC catalyst benefits the selective adsorption of the nitro group rather than other substituted groups, which efficiently avoids the undesirable side reactions. Importantly, the catalyst is stable and exhibits constant performances in the continuous recycling tests.

Simple, straightforward, and atom economic methods for the synthesis of quinolines, 2-aminoquinolines, and quinazolines via biomimetic dehydrogenative condensation/coupling reactions, catalyzed by well-defined inexpensive and easy to prepare singlet diradical Ni(II)-catalysts featuring two antiferromagnetically coupled singlet diradical diamine type ligands are described. Various polysubstituted quinolines, 2-aminoquinolines, and quinazolines were synthesized in moderate to good yields from different low-cost and readily accessible starting materials. Several control experiments were carried out to get insight into the reaction mechanism which shows that the nickel and the coordinated diamine ligands participate in a synergistic way during the dehydrogenation of alcohols.

An asymmetric phase-transfer-catalyzed N -alkylation of substituted indoles with various Michael acceptors was studied. Acidities of nitroindoles were determined in acetonitrile by UV-Vis spectrophotometric titration. There was essentially no correlation between acidity and reactivity in the aza-Michael reaction. The position of the nitro group on the indole ring was essential to control the stereoselectivity of the reaction. Michael adducts were obtained in high yields and moderate enantioselectivities in the reaction between 4-nitroindole and various Michael acceptors in the presence of cinchona alkaloid based phase-transfer catalysts. In addition to outlining the scope and limitations of the method, the geometries of the transition states of the reaction were calculated.
