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.

Noble metals play a momentous role in heterogeneous catalysis but still face a huge challenge in selectivity control. Herein, we report isolating contiguous Pt atoms and forming Pt-Zn intermetallic nanoparticles as an effective strategy to optimize the selectivity of Pt catalysts. Contiguous Pt atoms are isolated into single atoms and Pt-Zn intermetallic nanoparticles are formed which are supported on hollow nitrogen-doped carbon nanotubes (PtZn/HNCNT), as confirmed by aberration-corrected high-resolution transmission electron microscopy and X-ray absorption spectrometry measurements. Interestingly, this PtZn/HNCNT catalyst promotes the hydrogenation of 4-nitrophenylacetylene to 4-aminophenylacetylene with a much higher conversion (> 99%) and selectivity (99%) than the comparison samples with Pt isolated-single-atomic-sites (Pt/HNCNT) and Pt nanoparticles (Pt/CN). Further density functional theory (DFT) calculations disclose that the positive Zn atoms assist the adsorption of nitro group and Pt-Zn intermetallic nanoparticles facilitate the hydrogenation on nitro group kinetically.

The first naked (Lewis base-free) cationic Ca amidinate complex [(AmCa)-Am-tBu-Ca-DIPP(C6H6)](+)[B(C6F5)(4)](-) was prepared in 62 % yield {(AmDIPP)-Am-tBu = tBuC(N-DIPP)(2); DIPP = 2,6-diisopropylphenyl} by reaction of [(AmCaH)-Am-tBu-Ca-DIPP](2) with [Ph3C](+)[B(C6F5)(4)](-) in chlorobenzene. The ether-free complex (AmCaN)-Am-tBu-Ca-DIPP(SiMe3)(2) was obtained by removal of diethyl ether from its ether adduct. Crystal structures show that the amidinate ligand in both complexes is N,Aryl-chelating. In this coordination mode the bulk of the amidinate ligand is comparable to that of a DIPP-substituted beta-diketiminate ligand. Isomers with N,N-coordinating amidinate ligands are circa 15 kcal/mol higher in energy and this coordination mode is only present in case additional ether ligands compensate for energy loss or in case of space limitation at the metal, e.g. in homoleptic (Am-tBu(DIPP))(2)Ca. A series of four Ca amidinate complexes, (AmCaX)-Am-tBu-Ca-DIPP, were tested in the catalytic hydroboration of ketones and aldehydes by pinacolborane (HBpin). Catalytic activities increase for X- = I- < B(C6F5)(4)(-) < (Me3Si)(2)N- approximate to H-. For catalysts with unreactive anions, like I- or B(C6F5)(4)(-), catalyst performance increases with the Lewis acidity of the metal and a mechanism is proposed in which HBpin and ketone coordinate to the Ca2+ ion which is followed by direct hydroboration. The more active catalysts with X- = (Me3Si)(2)N- or H- likely operate through a mechanism which involves intermediate metal hydride (or borate) complexes.

A titanium.IV) oxide photocatalyst modified with 2,3-dihydroxynaphthalene (DHN/TiO2) responds to visible light, and electrons are photogenerated to the conduction band of TiO2 under light irradiation in the presence of a suitable hole scavenger. The reducing potential of DHN/TiO2 was applied for photocatalytic conversion of a nitro group to an amino group of aromatics having other reducible groups under hydrogenfree and noble metal-free conditions at room temperature. Various nitro aromatics having vinyl, chloro, bromo, and acetyl groups were converted to amino aromatics with high yields with the reducible groups being preserved. Some parameters affecting the catalytic performance were investigated, and the reaction rate was almost determined by the amount of the substrate adsorbed on DHN/TiO2.

Tandem ammonia borane dehydrogenation and nitroarenes hydrogenation has been reported as a novel strategy for the preparation of aromatic amines. However, the practical application of this strategy is subjected to the high-cost and tedious preparation of supported noble metal nanocatalysts. The commercially available CuO powder is herein demonstrated to be a robust catalyst for hydrogenation of nitroarenes using ammonia borane as a hydrogen source under mild conditions. Numerous amines (even sterically hindered, halogenated, and diamines) could be obtained through this method. This monometallic catalyst is characteristic of support-free, excellent chemoselectivity, low-cost, and high recyclability, which will favor its future utilization in preparative reduction chemistry. Mechanistic studies are also carried out to clarify that diazene and azoxybenzene are key intermediates of this heterogeneous reduction.

Utilization of abundantly available biomass to develop advanced materials and products has become an utmost priority these days. Herein, we developed a sustainable route for the synthesis of Ni nanoparticles loaded on N-doped carbon nanosheets using underutilized sugarcane bagasse, urea and NiCl2 center dot 6H(2)O as the carbon, nitrogen and Ni source. The synthesized catalyst was characterized using different analytical techniques; FESEM, elemental mapping and HRTEM analysis revealed the formation of flower-like carbon nanosheets containing uniformly distributed nickel nanoparticles with average particle size of 2.4-10 nm. The synthesized nanocatalyst was used for the one-pot reductive amination of different bio-derived aldehydes with the nitroarenes at 100 degrees C for 4 h. The complete conversion of the variety of nitroarenes with the formation of imines and benzimidazole products was obtained under optimized reaction conditions. The catalyst was recyclable up to five times with negligible loss in selectivity towards imines.

Supported platinum (Pt) catalysts present excellent chemoselectivity for a variety of hydrogenation reactions. Minimizing the use of such expensive catalysts while retaining their catalytic activities has been one of the most challenging topics in recent years. The construction of well dispersed, stable Pt single atom catalysts both increases the density of catalytically active sites while reducing Pt usage. Here we report the synthesis of Pt single atoms trapped in carbon onion graphitic shells by arc-discharge in aqueous solution. Such graphitic shells not only limit the chemical/thermal coarsening of Pt single atoms, but also enhance the conductivity for accelerating the penetration and exchange of ions and electrons during the catalytic process. Experimental results demonstrate that the Pt single atomcatalysts show superior performance and no detectable loss of activity and selectivity over 10 cycles (both remain >99%) for the hydrogenation of p-chloronitrobenzene. This novel atomically dispersed form of Pt catalyst is indicative of a new avenue towards efficient synthesis of single atom catalysts with improved performance. (C) 2018 Elsevier Ltd.

Methanol is a potential hydrogen source and C-1 synthon, which finds interesting applications in both chemical synthesis and energy technologies. The effective utilization of this simple alcohol in organic synthesis is of central importance and attracts scientific interest. Herein, we report a clean and cost-competitive method with the use of methanol as both C-1 synthon and H-2 source for selective N-methylation of amines by employing relatively cheap RuCl3.xH(2)O as a ligand-free catalyst. This readily available catalyst tolerates various amines comprising electron-deficient and electron-donating groups and allows them to transform into corresponding N-methylated products in moderate to excellent yields. In addition, few marketed pharmaceutical agents (e. g., venlafaxine and imipramine) were also successfully synthesized via late-stage functionalization from readily available feedstock chemicals, highlighting synthetic value of this advanced N-methylation reaction. Using this platform, we also attempted tandem reactions with selected nitroarenes to convert them into corresponding N-methylated amines using MeOH under H-2-free conditions including transfer hydrogenation of nitroarenes-to-anilines and prepared drug molecules (e. g., benzocaine and butamben) as well as key pharmaceutical intermediates. We further enable one-shot selective and green syntheses of 1-methylbenzimidazole using ortho-phenylenediamine (OPDA) and methanol as coupling partners.
