In contrast to conventional organoselenium-catalyzed oxidation reactions that require peroxide oxidants such as hydrogen peroxide, in this work we found that, addition of a low loading of iron (II) could enable the successful utilization of air as the terminal oxidant in organoselenium-catalyzed oxidative deoximation reaction of ketoximes. This led to a new mild and relatively green aerobic oxidative deoximation method. Control reactions and X-ray photoelectron spectroscopy (XPS) analysis suggest that iron is crucial in the catalytic cycle, working to prohibit the deactivation of selenium catalyst through an iron-catalyzed aerobic oxidation of low valent selenium species by air to the active high valent selenium species. Since air can be utilized as the terminal oxidant, this work may contribute to the advance of organoselenium catalysis.

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.

An efficient, reusable and stable binaphthyl stabilized Pd-nanoparticles (Pd-BNP) catalyzed the direct ortho-C-H hydroxylation of acetophenone oxime ethers under neutral and phosphine ligand-free condition has been developed. A readily available, economic, safe and greener oxidant oxone has been used in this direct ortho-hydroxylation. The scope of the reaction has been studied with various acetophenone oxime ethers including electron rich to electron deficient system and the reaction afforded only mono hydroxylated products in a highly regioselective manner. Several control experiment results confirmed that the oxone is the hydroxyl source. The Pd-BNP catalyst has been reused up to five times. The heterogeneous test confirmed that the reaction is catalyzed by the heterogeneous Pd-BNP catalyst.

Selective oxidation of aromatic alkanes by C-H activation is one of the key reactions in organic synthesis and the chemical industry. Activation of C-H bonds to obtain high-value added products under mild conditions by using sustainable carbocatalysts is of particular interest. Herein, we report a sustainable, green and template-free strategy towards the fabrication of N-doped and N/S codoped carbon nanosheets by metal-free carbonization of bioprecursors guanine and guanine sulfate. The formation of thin and N/S codoped carbon nanosheets was induced by multiple interactions of the nucleobases. Benefiting from the unique textural structure of the as-synthesized carbons, including ultrathin thickness, optimal porosity, and rich structural defects, and the synergistic coupling effect of multiple dopants, the carbon nanosheets show a high catalytic performance with 85% ethylbenzene conversion and 98% selectivity to acetophenone at 80 degrees C after 4 h reaction, which outperforms other equivalent benchmarks (e.g. 8.5 times higher conversion and 3.2 times higher selectivity than those of oxidized carbon nanotubes). Density functional theory simulations indicate that the oxidation of ethylbenzene is catalyzed by the synergistic effect of p-N/S and g-N/S catalysts via an OH radical mechanism. This N/S codoped strategy provides guidance for the design of carbon-based catalysts for the selective oxidation of other alkanes.

The Pd-catalyzed decarboxylation and dual C(sp(3))-H bond functionalization approaches have been described for the preparation of symmetrical and unsym-metrical 2,4-diarylpyridines. The developed transformations were realized using nonactivated aromatic ketones and amino acids as C-N sources. The efficacy of the catalyst and reagent combination drives the transformation toward the formation of desired products with high yields and selectivity. The described reaction conditions have seduced the self-reaction of phenylalanine via [2 + 2 + 2] cycloaddition and minimized the formation of 3,5-phenylpyridine as a side product, whereas using glycine as a C-N source, the corresponding 2,6-diarylpyridines were formed as minor products.

As the global need for drugs getting increases, the necessity of novel and effective drugs are the need of the day. Pyrazoles are one of the active molecules in novel drug discovery. The present study deals about the synthesis of precursors 4-(4-fluorophenyl)-6-isopropyl-2-(methylsulfonyl) pyrimidine-5-carbohydrazides (3a-m) from methyl- 4-(4-fluorophenyl)-6-isopropyl-2-(methyl sulfonyl) pyrimidine-5-carboxylate (2) by treating with substituted acetophenone. Further, Vilsmeier-Haack reaction of compounds 3a-m at 70 degrees C for 8-10 hrs gave novel pyrazole carbaldehyde derivatives (4a-m) in good yield. Biological properties like antioxidant, anti-breast cancer and anti-inflammatory of newly synthesized compounds (4a-m) were determined. The enzymes Cyclooxygenase-2 and Phosphoinositide-3-Kinase are most responsible for the corresponding diseases such as inflammation and breast cancer respectively. In order to examine the interaction between these two enzymes and our synthesized compounds 4a-m, molecular docking study was carried out. From the results, few compounds of 4a-m were found to have anti-inflammatory properties by showing excellent COX-2 inhibition and HRBC membrane stabilization properties. ADMET prediction results were also valuable to screen the most effective pyrazole derivatives to establish them as future COX-2 inhibitors or anti-inflammatory drugs.

Hydrofunctionalization, the direct addition of an X-H (e.g., X=O, N) bond across an alkene, is a desirable strategy to make heterocycles that are important structural components of naturally occurring molecules. Described here is the design and discovery of donor-acceptor-type platinum catalysts that are highly effective in both hydroalkoxylation and hydroamination of unactivated alkenes over a broad range of substrates under mild conditions. A number of alkene substitution patterns are accommodated, including tri-substituted, 1,1-disubstituted, (E)-disubstituted, (Z)-disubstituted and even mono-substituted double bonds. Detailed mechanistic investigations suggest a plausible pathway that includes an unexpected dissociation/re-association of the electron-deficient ligand to form an alkene-bound donor-acceptor-type intermediate. These mechanistic studies help understand the origins of the high reactivity exhibited by the catalytic system, and provide a foundation for the rational design of chiral catalysts towards asymmetric hydrofunctionalization reactions. The direct addition of an O-H (hydroalkoxylation) or an N-H (hydroamination) bond across an alkene is a useful strategy to access biologically relevant heterocycles. Here, the authors report donor-acceptor-type platinum catalysts that are effective for both hydroalkoxylation and hydroamination of unactivated alkenes, with broad substrate scope and use of mild conditions.

The title compounds, 3,3′,3.,3”’-[methylenebis(oxybenzene-5,1,3-triyl)]tetrakis(6,8-diaryl[1,2,4]triazolo[3,4-b][1,3,4]thiadiazepines), were synthesized starting from dimethyl 4-hydroxyisophthalate which was reacted with dibromomethane to obtain tetramethyl 5,5′-[methylenebis(oxy)]di(benzene-1,3-dicarboxylate). The latter was treated with excess hydrazine hydrate, and the resulting tetrahydrazide was converted to tetrakis1,2,4-triazolyl derivative via cyclization with ethanolic potassium hydroxide, carbon disulfide, and hydrazine hydrate. In the final stage, cyclocondensation with substituted chalcones afforded the target products. The structure of the newly synthesized compounds was confirmed by elemental analyses and FT-IR and NMR spectra, and their antimicrobial activities against some bacterial and fungal strains were estimated by the disc diffusion method.

Imidazolin-2-iminato hafnium complexes of the type [(Im (R) N)Hf(CH2Ph)(3)] were synthesized (Im(tBu)N = 1,3-di-tert-butylimidazolin-2-iminato); Im(Dipp)N = 1,3-bis(2,6-diisopropylphenyl)-imidazolin-2-iminato. The complexes were crystallized and structurally characterized. Despite the oxophilicity of the hafnium center, both hafnium complexes were catalytically active in the hydroboration of aldehydes, ketones, and carbodiimides. Herein, we present the influence of different substrates bearing electron-withdrawing or electron-donating groups on the catalytic reactions.
