Modification of active metals with metal oxide modifiers has attracted considerable attention in heterogeneous catalysis due to their synergistic effect. However, a controllable synthesis of highly reactive and stable metal-metal oxide hybrid nanocatalysts is difficult. To solve this problem, presynthesized IrM (M = Fe, Co, and Ni) bimetallic nanoparticles were initially confined in the mesopores of SBA-15 and were then in situ transformed to Ir-MOx hybrids. The obtained Ir-MOx/SBA-15 nanocatalysts show superior activity and selectivity in the hydrogenation of substituted nitroaromatics to corresponding aromatic amines compared to Ir/SBA-15. Among these Ir-based catalysts, Ir-FeOx/SBA-15 exhibits the highest activity and selectivity and has a wider substrate scope due to the interaction between Ir and FeOx. Therefore, our research provides a way to design reactive and stable hydrogenation catalysts.

The stereoselective beta-C(sp(2))H arylation of various acyclic enamides with arylsilanes via Rh(III)-catalyzed cross-coupling reaction was illustrated. The methodology was characterized by extraordinary efficacy and stereoselectivity, a wide scope of substrates, good functional group tolerance, and the adoption of environmentally friendly arylsilanes. The utility of this present method was evidenced by the gram-scale synthesis and further elaboration of the product. In addition, Rh(III)-catalyzed C-H activation is considered to be the critical step in the reaction mechanism.

This work deals with the synthesis, spectroscopic studies and catalytic evaluation of the novel chiral salen (L1H2) and (L2H2) ligands and their chiral boronate [L-1(B1-4)] and [L-2(B1-4)] complexes. Initially, the reaction of 5-azidomethyl salicylaldehyde and (R)-(-)-2-amino-1-butanol in absolute ethanol afforded a new chiral salen ligand (L1H2). Then, a novel chiral salen ligand (L2H2) have been prepared from chiral salen ligand (L1H2) for the synthesis of boronate [L-2(B1-4)] complexes through click reaction approach under ambient conditions. The reaction of chiral salen (L1H2) and (L2H2) ligands with various boronic acids afforded a new tetra-coordinated mononuclear chiral boronate [L-1(B1-4)] and [L-2(B1-4)] complexes. All the compounds are remarkably stable crystalline solids and were obtained in good yields. For the full characterization of newly synthesized chiral salen ligands and their boronate complexes, the FT-IR, UV-Vis, NMR (H-1, C-13, and B-11), LC-MS, and elemental analysis techniques have been used. The well-shaped chiral boronate compounds were investigated as catalyst for the asymmetric transfer hydrogenation (ATH) of aromatic ketones under appropriate settings. Particularly, it was proved that the ferrocene-based boronate compounds can afford an efficient catalytic conversion compared to the other boronate complexes in the asymmetric transfer hydrogenation catalytic studies.

In this study, a novel diamine monomer, 4-(4-trifluoromethylthiophenyl)-2,6-bis(4-aminophenyl)pyridine (FTPAP) was synthesized through two-step reaction from 4-trifluoromethylthiobenzaldehyde and 4-nitroacetophenone as raw materials, and then the structure of FTPAP was characterized by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance, and mass spectrometry. A series of fluorinated polyimides were prepared from FTPAP with five commercial dianhydrides, namely, pyromellitic dianhydride, biphenyl tetracarboxylic dianhydride, oxydiphtahalic anhydride, benzophenone tetracarboxylic dianhydride, and 4,4 ‘-(hexafluoroisopropylidene) diphthalic anhydride. The structure and performance of the fluorinated polymers were fully characterized by FTIR, differential scanning calorimetry, thermogravimetric analysis, and wide-angle X-ray diffraction (WAXD). The inherent viscosity of polymers ranged from 0.41 to 1.45 dL g(-1). These polymers displayed good solubility in polar aprotic solvents, such as N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, and N-methyl-2-pyrrolidone, at room temperature or on heating. Furthermore, they exhibited outstanding thermal stability with glass transition temperatures beyond 305 degrees C, and the temperature of 10% weight loss was in the range of 514-573 degrees C with more than 56% residue at 800 degrees C under nitrogen. Moreover, they showed high optical transparency with the cutoff wavelengths in the range of 385-457 nm and excellent hydrophobic property with contact angle in the range of 82.8-97.6 degrees. In addition, the results of WAXD indicated that all of the polymers presented amorphous structure.

We report carbonyl-stabilized phosphorus ylides as general and efficient catalysts for the cyanosilylation of ketones. The N,N-diethylacetamide derived phosphorane is identified as an extremely efficient catalyst for the cyanosilylation of dialkyl ketones, alkyl aryl ketones, diaryl ketones, and alpha,beta-unsaturated enones with catalyst loading down to 0.005 mol %, the lowest ever known for ketone cyanosilylation. Aldehydes, aldimines, and ketimines are also viable substrates. By NMR and React IR analysis, as well as electrical conductivity experiments, it is proposed that the phosphorane acts as a Lewis base in order to mediate the reaction via the desilylative nucleophilic activation of TMSCN.

Aim: Identification of new, effective and selective trypanocidal agents. Materials & methods: Twelve novel acetohydroxamic acid derivatives based on 2-alkyl-2-aryl-2,6-diketopiperazine scaffolds have been synthesized and evaluated in vitro for their growth inhibitory activity against bloodstream form Trypanosoma brucei. Results: All the analogs were remarkably potent inhibitors, with low micromolar to submicromolar activities. Structure-activity relationship studies demonstrated that the presence of an alkyl substituent at the N(4)-position of the 2,6-diketopiperazine ring portion was, in general, beneficial to trypanocidal activity in this series. Conclusion: The highest activity resulted from the introduction of a methyl, n-propyl or n-butyl substituent to the N(4)-position of the parent compound. Importantly, the most potent analogs were found to be highly selective against T brucei with respect to mammalian cells. [GRAPHICS] .

The transition metal free reduction of aromatic/heteroaromatic nitro compounds to amines has been improved employing phenyl(2-quinolyl)methanol (PQM) as organocatalyst in the presence of NaBH(4)or NaCNBH(3)as stoichiometric reducing agent. The procedure is chemoselective for NO(2)group reduction with high tolerance of many functionalities. The reaction pathway strongly depends on the substituents present on the nitroarene ring. However, a careful choice of the reaction conditions allows to address the reduction process towards the corresponding anilines (isolated in 17-91 % yields). The use of substoichiometric amounts of PQM allows more sustainable processes: reaction products are easily isolated and PQM can be directly recovered at the end of the reaction and recycled.

We have identified a novel one-pot method for the synthesis of beta-amino alcohols, which is based on C-H bond hydroxylation at the benzylic alpha-carbon atom with a subsequent nitrile or amide functional group reduction. This cascade process uses molecular oxygen as an oxidant and sodium bis(2-methoxyethoxy)aluminum hydride as a reductant. The substrate scope was examined on 30 entries and, although the respective products were provided in moderate yields only, the above simple protocol may serve as a direct and powerful entry to the sterically congested 1,2-amino alcohols that are difficult to prepare by other routes. The plausible mechanistic rationale for the observed results is given and the reaction was applied to a synthesis of a potentially bioactive target.

Twelve new chiral chelating resins have been prepared using solid phase organic synthesis with the Merrifield and Wang resins and the bidentate amine 1,2-ethylenediamine, followed by the coupling of asymmetric ketones such as 1-phenyletanone, 4-methyl-2-pentanone 4-nitroacetophenone and 4-methoxyacetophenone to form prochiral imines. The enantioselective reduction with borane and (R)-(+)-2-Methyl-CBS-oxazaborolidine leads to the chiral resins with yields greater than 86%. We used these chiral resins to prepare 24 reducing complexes with alkali tetrahydroborates in a very simple way giving yields greater than 87%. Finally, we achieved a preliminary enantioselective reduction of acetophenone employing the Merrifield’s chiral chelating resins obtaining the corresponding S alcohol in a 70:30 ratio with the R analog alcohol.
