This work illustrates direct evidence of the formation of close-contact Rh-SnO2 heteroaggregate interfaces, and their enhanced catalytic hydrogenation performance is also demonstrated. Alumina-supported Rh-SnO2 heteroaggregate nanocatalysts were prepared by in situ transformation of Rh@Sn core-shell nanostructures. Various characterization techniques, especially the studies of high angle annular dark field scanning transition electron microscopy with phase mappings, confirm that Rh-SnO2 close-contact heteroaggragate nanostructures were obtained by in situ calcination and following reduction of Rh@Sn core-shell nanoparticle precursors. The catalytic studies for hydrogenations of various substituted nitroaromatics show that the Rh-SnO2/Al2O3 heteroaggregate nanocatalysts not only improve the catalytic conversions but also enhance the catalytic selectivity. The combination of characterization and catalytic studies suggests that a synergistic effect originated from close-contact Rh-SnO2 heteroaggregate interfaces exists in the Rh-SnO2 system, which enhances their catalytic hydrogenation performance.

Chemoselective hydrogenation of nitroarenes to anilines is of great importance for the manufacture of pharmaceuticals, fine chemicals, and dyes. In this study, a series of metal-free N-doped carbon nanotubes (NCNTs) have been prepared by the carbonization of in situ polymerized pyrrole on CNTs. The concentration of pyrrole, pyrolysis temperature, and the outside diameter of CNTs were investigated to improve the catalytic performance. As characterized by Raman and X-ray photoelectron spectroscopy (XPS), the optimal catalyst (NCNTs-800) possessed a unique structure doped with the same content of pyrrolic N and graphitic N. The activity and selectivity of NCNTs-800 have been evaluated for the selective hydrogenation of substituted nitroarenes. Highly selective hydrogenation of the nitro group of 12 different substrates has been achieved on NCNTs-800, even in the presence of a fragile iodo group. The hydrogenation reaction on N-doped CNTs from polypyrrole involved a mixture of different hydrogen species including nonpolar H radicals. In addition, stability and recyclability of NCNTs-800 have been tested.

An efficient radical-mediated carbon-sulfur bond formation reaction of vinyl halides with thiols has been developed. This reaction tolerated vinyl chloride substrates, which are barely tolerated in metal-catalyzed reactions, providing vinyl sulfide products. When vinyl iodides were used as substrates, the reactions were regulated by the solvents, yielding vinyl sulfide products in protic solvents (methanol) and alkyl sulfides in aprotic solvents (toluene).

Emulating the function of natural carboxylases to convert CO(2)under atmospheric condition is a great challenge. Herein we report a class of CO2-folded single-chain nanoparticles (SCNPs) that can function as recyclable, function-intensified carboxylase mimics. Lewis pair polymers containing bulky Lewis acidic and basic groups as the precursor, can bind CO(2)to drive an intramolecular folding into SCNPs, in which CO(2)as the folded nodes can form gas-bridged bonds. Such bridging linkages highly activate CO2, which endows the SCNPs with extraordinary catalytic ability that can not only catalyze CO2-insertion of C(sp(3))-H for imitating the natural enzyme’s function, it can also act on non-natural carboxylation pathways for C(sp(2)and sp)-H substrates. The nanocatalysts are of highly catalytic efficiency and recyclability, and can work at room temperature and near ambient CO(2)condition, inspiring a new approach to sustainable C(1)utilization.

A series of robust metallo-aerogels are readily fabricated by pyrolysis of xerogels derived from chitosan-metal (M = Fe, Co, Ni) hydrogels. Owing to the strong coordination between metal ions and the functional groups (NH2 and OH) of chitosan, metallo-aerogels consisting of encapsulated metal-nanoparticles (MNPs) by graphite shells were obtained, as supported by various characterizations including high-resolution transmission electron microscope (HR-TEM), X-ray diffraction (XRD), and Raman. The resulting metallo-aerogels could be functioned as highly stable, efficient and selective nanocatalysts towards the hydrogenation of nitroarenes to amines at low catalyst loading (1.2 mol.%-2.4 mol.%). Remarkably, the metallo-aerogels could be reused for more than 30 runs without obvious loss of activity and selectivity. These distinguished performances were attributed to the graphitic shells formed during the pyrolysis, which hampered the possible aggregation of MNPs, prevented metal leaching and increased their stability.

An efficient and facile approach has been described for the synthesis of a new series of 1-amino-2-oxo-nicotinonitriles and their sulfonamides under microwave and ultrasonic irradiation. The desired compounds 4 a-l were obtained via condensation of p-chlorobenzaldehyde, aryl or heteroaryl methyl ketone and cyanoacetohydrazide in the presence of catalytic piperidine under three synthetic methodologies (namely, conventional method, ultrasonic and microwave irradiation), the best results (short reaction times, pure products, high yield) were obtained by ultrasonic irradiation. Sulfonamides 5 a-f resulted via reaction of amines 4 a-e and 4 j with benzene sulfonyl chloride in the presence of pyridine. The synthesized compounds give no significant results when investigated against Gm (+ve) and Gm (-ve) bacteria, and fungi strains.

A novel diamine monomer 4-(4-diethylaminophenyl)-2,6-bis(4-aminophenyl)pyridine (APAP) was successfully synthesized, and then a series of poly(pyridine imide)s was prepared from APAP with five commercial dianhydrides: pyromellitic dianhydride (PMDA), 3,3,4,4-biphenyltetracarboxylic dianhydride (BPDA), 4,4-oxydiphthalic anhydride (ODPA), 3,3,4,4-benzophenone tetracarboxylic dianhydride (BTDA), and 4,4-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) via a two-step solution polycondensation method. The structure of APAP was characterized by FT-IR, NMR, and MS. The resulting polymers have good solubility in polar solvents, such as NMP, DMF, and DMSO. Furthermore, they exhibited outstanding thermal stability. The glass transition temperature (T-g) of polymers range from 326 to 346 degrees C, and the temperature at 5 % and 10 % weight loss in the range of 527 degrees C to 570 degrees C and 550 degrees C to 601 degrees C, respectively. Moreover, they also presented excellent hydrophobicity with contact angels in the range of 88.4 degrees to 94.0 degrees.

In this work, N-Cbz hydrazone has been employed as a rarely explored directing group for the synthesis of isoquinolines by annulation with internal alkynes via C-H/ N-N activation using Ru catalyst. Additive as well as external oxidant-free rapid protocol has been established for the synthesis of isoquinolines using microwave strategy. Use of non-volatile and biodegradable PEG as a green solvent with lower catalyst loading makes the proposed protocol environmentally benign. Further, higher functional group tolerance and wide substrate scope has been observed under the stated methodology with higher yields.

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.

Single-atom catalysts (SACs) have attracted significant attention because they exhibit unique catalytic performance due to their ideal structure. However, maintaining atomically dispersed metal under high temperature, while achieving high catalytic activity remains a formidable challenge. In this work, we stabilize single platinum atoms within sub-nanometer surface cavities in well-defined 12CaO7Al(2)O(3) (C12A7) crystals through theoretical prediction and experimental process. This approach utilizes the interaction of isolated metal anions with the positively charged surface cavities of C12A7, which allows for severe reduction conditions up to 600 degrees C. The resulting catalyst is stable and highly active toward the selective hydrogenation of nitroarenes with a much higher turnover frequency (up to 25772h(-1)) than well-studied Pt-based catalysts. The high activity and selectivity result from the formation of stable trapped single Pt atoms, which leads to heterolytic cleavage of hydrogen molecules in a reaction that involves the nitro group being selectively adsorbed on C12A7 surface. Stabilize the active metal single atoms under harsh conditions is critical for the development of single atom catalysts. Here the authors report a nanoporous crystal, 12CaO7Al(2)O(3), that can firmly stabilize Pt single atoms in its surface cavities for efficient catalytic hydrogenation of nitroarenes.
