A triflatostannylene [(LSn)-Sn-dagger(ii)][OTf] (2) is reported here as an efficient catalyst with low-valent main-group element for the hydroboration of aldehydes and ketones (L-dagger = aminotroponate). Using 0.025-0.25 mol% of compound 2, hydroboration of various aldehydes and ketones is accomplished in 0.13-1.25 h at room temperature; the aliphatic aldehydes show an impressive TOF of around 30000 h(-1). DFT calculations are performed to explore the mechanistic aspects of this reaction suggesting that the reaction proceeds via a stepwise pathway with hydridostannylene [(LSn)-Sn-dagger(ii)H] (2a) as the active catalyst and the H atom transfer from the Sn-H bond to the carbonyl carbon being the rate determining step.

Four new series of aromatic sulfamates were synthesized and investigated for the inhibition of four human (h) isoforms of zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), hCA I, II, IX, and XII. The reported derivatives, obtained by a sulfamoylation reaction of the corresponding phenolic precursors, bear 3,5-diarylpyrazoline moieties as spacers between the benzenesulfamate fragment which binds the zinc ion from the active site, and the tail of the inhibitor. Pyrazolines are biologically privileged scaffolds, endowed with versatile biological activity, such as an anti-proliferative action. The derivatives were tested for the inhibition of the cytosolic, hCA I and II (off target isoforms) and the trans-membrane, tumor-associated hCA IX and XII enzymes (anticancer drug targets). Generally, hCA I was not effectively inhibited, whereas many low nanomolar inhibitors were evidenced against hCA II (KIs in the range of 0.42-90.1 nM), IX (KIs in the range of 0.72-63.6 nM), and XII (KIs in the range of 0.88-85.2 nM). The best substitution fragments at the pyrazoline ring included for CA it a 4-sulfamic group on the 3-aryl and halogens on the 5-aryl or a methoxy group on the 3-aryl and a 4-sulfamate group on the 5-aryl; for CA IX and CA XII they included the sulfamic group on the 3- or 4-position of the 5-aryl and an electronwithdrawing group on the 4-postion of the 3-aryl ring.

Recently I am researching about CHEMOSELECTIVE REDUCTION; ORGANIC-SYNTHESIS; CU NANOPARTICLES; NANOCATALYST; NITRO; HYDROGENATION; EFFICIENT; AMINES, Saw an article supported by the research council of Urmia University, Urmia University, Iran [68-161]. Published in BENTHAM SCIENCE PUBL LTD in SHARJAH ,Authors: Sadeghbari, M; Zeynizadeh, B; Pesyan, NN. The CAS is 100-19-6.

Aim and Objective: Nowadays, the design, synthesis and application of magnetically nanocomposite systems have attracted the attention of numerous scientists. The huge surface area and magnetic characteristic of nanoparticles as well as the inherent potentiality of the used metal species, makes them susceptible to have different reactivity in chemical reactions. In this context, we therefore encouraged to prepare a new design of magnetic nanocatalysts as CuFe2O4@SiO2@AAPTMS@Ni(II) and CuFe2O4@SiO2@AAPTMS@Cu(II) followed by monitoring of their catalytic activities towards reduction of nitroarenes with NaBH4. Materials and Methods: Magnetically nanoparticles of CuFe2O4@SiO2@AAPTMS@Ni(II) and CuFe2O4@SiO2@AAPTMS@Cu(II) were prepared through a four-step procedure: i) preparation of CuFe2O4 MNPs, ii) coating of CuFe2O4 nucleus by silica-layer using tetraethyl orthosilicate (TEOS), iii) layering of CuFe2O4@SiO2 MNPs with [3-(2-aminoethylamino)propyl] trimethoxysilane (AAPTMS), and iv) the complexation of CuFe2O4@SiO2@AAPTMS MNPs with an aqueous solution of Ni(OAc)(2)center dot 4H(2)O or Cu(OAc)(2)center dot H2O. Results: The catalytic activity of CuFe2O4@SiO2@AAPTMS@AAPTMS@Ni(II) and the Cu(II)-analogue towards reduction of nitroarenes with NaBH4 was studied. The examinations resulted that using a molar ratio of 1:2 for ArNO2 and NaBH4 in the presence of 20 mg of nanocomposites in H2O under reflux conditions reduces various aromatic nitro compounds to arylamines in high yields. Conclusion: The immobilization of Ni(II) and Cu(II) species on silica-layered CuFe2O4 was investigated. Magnetically nanoparticles of CuFe2O4@SiO2@AAPTMS@Ni(II) and the Cu(II)-analogue showed the perfect catalytic activity towards reduction of nitroarenes with NaBH4, in H2O. All reactions were carried out within 2-15 min to afford aniline products in high yields.

A [3+1+1+1] cycloaddition was developed among 2-arylpropene, ketone and DMSO in the presence of K2S2O8. 2-arylpropene provides three carbons, ketone offers one carbon, and DMSO as dual carbon donor contributes two carbons to the six-membered carbocycle. It gave the cyclohexene motif and spirocyclohexene skeleton. Four C-C bonds formed in this process. Both propylene and ketone could be well tolerated and give the corresponding cyclohexene or spirocyclohexene motif in useful yields. Based on the controlled experiments, a possible mechanism was proposed.

A visible-light-promoted synthesis of quinoxalin-2(1H)-ones has been developed using 9-mesityl-10-methylacridinium perchlorate as an organo-photocatalyst. The atmosphere-controlled method (Ar/air) enabled the selective synthesis of hydroxyl- and acyl-containing quinoxalin-2(1H)-ones under mild reaction conditions without the use of any metal catalysts or toxic reagents. A fluorescent labelling experiment showed that hydroxyl-containing quinoxalin-2(1H)-ones may have utility in various biological applications as potent fluorophores.

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.

Visible-light active, heterogeneous, and organic photocatalysts exhibit a more sustainable and environmentally friendly alternative to classical metal-based catalysts. Two-dimensional covalent organic frameworks (2D-COFs) with permanent porosity, columnar It-arrays and excellent stability, that can become an excellent platform for heterogeneous photocatalysis of organic transformations. Here we report a predesigned imine-based COF with electron donor and acceptor structure. And new framework possesses large surface area, high crystallinity, outstanding stability and broad absorption range in the visible-light region as well as good photoelectric response characteristics. Importantly, it was found to be a highly effective heterogeneous photocatalyst for reductive dehalogenation of phenacyl bromide derivatives and cc-alkylation of aldehydes under irradiation of visible-light. In addition, the COF gave good recyclability and could be reused after a simple separation manipulation. The current present still reveals a great prospect for 2D-COFs as metal-free, heterogeneous photo catalysts for organic transformations.

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.
