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.

Diarylfluoromethyl sulfonium salts are efficient fluoromethylene transfer reagents equivalent to fluorocarbene, which is difficult to access. This was demonstrated by the development of a monofluorinated Johnson-Corey-Chaykovsky reaction with ketones and aldehydes, delivering uncommon 2-unsubstituted fluoroepoxides. This is the first evidence for the feasibility of sulfur fluoromethylylide and its action as a reaction intermediate.

A group of new polyimides (PIs) containing xanthene bulky groups and heterocyclic pyridine ring were synthesized by polycondensation reaction by using new symmetric and asymmetric diamines with available dianhydrides. The prepared diamines and PIs were characterized by Fourier transform infrared, elemental analysis, and proton nuclear magnetic resonance spectroscopy and carbon nuclear magnetic resonance spectroscopy. The PIs have desirable solubility in common aprotic solvents like dimethyl sulfoxide, N-methyl-2-pyrrolidone, dimethylacetamide, and pyridine as a less polar solvent. The PIs with inherent viscosities in the range of 0.51-0.72 dL/g were amorphous in nature, showed glass transition temperatures (T(g)s) of about 270-300 degrees C, and 10% weight loss at temperatures 384-443 degrees C. They showed fluorescence emission (quantum yield 7-12%) due to the presence of xanthene and pyridine groups in their structure. The prepared PIs showed tensile strength of 81-91 MPa with elongation at break of 19-23%. The antibacterial properties of the PIs against Gram negative and Gram positive bacteria and funguses were investigated. Also, a membrane of PI prepared by electrospinning method was used for the removal of different concentrations of Cr(VI) from aqueous solutions.

An efficient continuous flow process for the synthesis of 5-substituted 1H-tetrazoles is described. The process involves the reaction between a polymer-supported triorganotin azide and organic nitriles. The polymer-supported organotin azide, which is in situ generated with a polystyrene-supported triorganotin alkoxide and trimethylsilylazide, is immobilized in a packed bed reactor. This approach is simple, fast (it takes from 7.5 to 15 min), and guarantees a low concentration of tin residues in the products (<5 ppm). The process was developed to aryl-, heteroaryl-, and also alkylnitriles and was applied for the synthesis of valsartan, an angiotensin II receptor antagonist. HPLC of Formula: C14H11N.

We report an iodoarene-catalyzed enantioselective synthesis of beta,beta-difluoroalkyl bromide building blocks. The transformation involves an oxidative rearrangement of alpha-bromostyrenes, utilizing HF-pyridine as the fluoride source and m-CPBA as the stoichiometric oxidant. A catalyst decomposition pathway was identified, which, in tandem with catalyst structure-activity relationship studies, facilitated the development of an improved catalyst providing higher enantioselectivity with lower catalyst loadings. The versatility of the difluoroalkyl bromide products was demonstrated via highly enantiospecific substitution reactions with suitably reactive nucleophiles. The origins of enantioselectivity were investigated using computed interaction energies of simplified catalyst and substrate structures, providing evidence for both CH-pi and pi-pi transition state interactions as critical features.

A general strategy to synthesize mesoporous and macroporous carbon and N-doped mesoporous carbon is presented. The immobilization of cobalt catalysts with dispersed subnanometer particles in mesoporous N-doped carbon matrixes is also shown. These materials were used as catalysts for the hydrogenation of nitroarenes under considerably mild conditions. The surface area and the presence of nitrogen on the supports were demonstrated to be fundamental to disperse and stabilize the active metal species, which were responsible for the outstanding performance of these materials compared to cobalt catalysts deposited on silica, alumina, or mesoporous carbon. Finally, the ability to catalyze the hydrogenation of nitroarenes containing electron-donating groups (EDGs) and electron-withdrawing groups (EWGs) with good selectivity was also explored.

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.
