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. Category: benzodioxans.

Complex OsH6((PPr3)-Pr-i)(2) is an efficient catalyst precursor for the addition of pinacolborane and catecholborane to the C-N triple bond of alkyl nitrites. In this way, a variety of N,N-diborylamines have been isolated and fully characterized, including 13 derivatives not described so far. The range of nitrites used is wide and comprises substrates having unfunctionalized linear and branched chains, and functionalized chains with methoxide, trifluoromethyl, aryl, pyridyl, benzoyl, or cyanide groups. Kinetic studies demonstrate that the overall process consists of two consecutive irreversible reactions: the catalytic metal-promoted monohydroboration of the nitrile to afford the borylimine and the metal-free stoichiometric hydroboration of the latter to give the diborylamine. The mechanism of the hydroboration has been established by combining the kinetic analysis of the catalysis, stoichiometric reactions, and DFT calculations. The rate-determining step of the catalysis is the insertion of the C-N triple bond of the nitrite into the Os-B bond of an osmium-sigma-borane intermediate and is regiodirected by the nucleophilicity of the nitrogen atom and the electrophilicity of the carbon atom of the nitrite.

Covalent organic frameworks (COFs) are applied widely in organic catalysis; however, no precedent has been reported in polymerization catalysis. Herein, we report the new application of COFs for polymerization catalysis. Different amounts of homogeneous Rh catalyst are incorporated into the COF via post-treatment to give a series of TPB-DMTP-COF-X wt % Rh (b-e) containing varying amounts of Rh from 2.74 to 11.38 wt %. In contrast to the known Rh catalysts, TPB-DMTP-COF-X wt % Rh (b-e) display an uncommon synergistic effect and exceptional steric confinement effect of nanochannels. Therefore, they possess the advantages of both homogeneous catalysts in high activity and selectivity and heterogeneous catalysts in stability and recyclability with extremely high activity up to 1.3 x 10(7) g . mol(Rh)(-1)center dot h(-1) and cis-selectivity up to 99% and can be readily recycled and reused five times in the polymerization of phenylacetylene and its derivatives, affording cis-transoidal polyphenylacetylene and its derivatives having helical structures, aggregation-induced emission properties, or fluorescence properties with narrow molecular weight distributions.

The selective hydrogenation of nitro compounds into their corresponding azo compounds is challenging in organic synthesis. In this study, we have developed a facile and efficient catalytic system for the transformation of nitro compounds into azo compounds under mild conditions over a heterogeneous cobalt catalyst (Co-N-x/C-800-AT). The Co-N-x/C-800-AT catalyst was found to be highly active for the reductive-coupling of nitro compounds into azo compounds in ethanol at 110 degrees C and 2.5 bar H-2 pressure with the addition of NaOH as an additive, affording structurally-diverse azo compounds with satisfactory yields (70.4-98.3%). The developed method demonstrated several advantages such as high catalytic activity and high selectivity with tolerance to other functional groups and high stability.

A series of robust metallo-aerogels are readily fabricated by pyrolysis of xerogels derived from chitosan-metal (M = Fe, Co, Ni) hydrogels. Owing to the strong coordination between metal ions and the functional groups (NH2 and OH) of chitosan, metallo-aerogels consisting of encapsulated metal-nanoparticles (MNPs) by graphite shells were obtained, as supported by various characterizations including high-resolution transmission electron microscope (HR-TEM), X-ray diffraction (XRD), and Raman. The resulting metallo-aerogels could be functioned as highly stable, efficient and selective nanocatalysts towards the hydrogenation of nitroarenes to amines at low catalyst loading (1.2 mol.%-2.4 mol.%). Remarkably, the metallo-aerogels could be reused for more than 30 runs without obvious loss of activity and selectivity. These distinguished performances were attributed to the graphitic shells formed during the pyrolysis, which hampered the possible aggregation of MNPs, prevented metal leaching and increased their stability.

In the present study, an innovative cold plasma treatment was used as a tool to fortify the white rice. The amounts of ferrous sulphate and ascorbic acid were optimized for improving the bioavailability of iron. White rice samples were treated with plasma at a constant voltage of 20 kV for varying time (10 min and 15 min). The exposure time of plasma was selected based on the surface characteristics, hydrophilicity and thermal properties. Significant improvement was observed in the characteristics of hydrophilicity, surface energy, cooking time and hardness of plasma-treated rice. Plasma treated rice was fortified with the optimum concentrations of iron and ascorbic acid solution. Optimum concentrations of iron and ascorbic acid per 100 g of rice (862.93 mg and 1398.27 mg) were found by conducing experiments using Central Composite Design of Response Surface Methodology. Further, rice was blended with untreated rice in the ratio of 1:100 and 1:200 and was packed in LDPE and PP pouches and was stored at ambient temperature for further storage analysis. The in vitro bioavailability of iron was significantly higher in the plasma-treated fortified rice at both 1.35 and 7.5 pH than in the control sample, and plasma treatment significantly reduced the rate of oxidation of iron during storage.

Eight heteroleptic nickel(II) and copper(II) complexes of the type [M(L1-4)(nap)(2)] (1-8), where L1-4 = 2-(1-(4-substitutedphenyl)ethylidene)-hydrazinecarbothioamide, nap = naproxen, and M = Ni(II) or Cu(II), have been synthesized and characterized. UV-vis and EPR spectral studies showed distorted octahedral geometry around metal(II) ions. The cyclic voltammogram of complexes 1-8 displayed an irreversible one-electron transfer process in the cathodic region (E-pc = -0.66 to -1.43 V), and nickel(II) complexes 1-4 displayed an irreversible one-electron oxidation process in the anodic region (E-pa = 0.75 to 1.10 V). The obtained magnetic moment values (1.82-1.93 mu(B)) for copper(II) complexes 5-8 indicate distortion from octahedral geometry, which is further supported by EPR studies. The geometry of the complexes is retained in both solid and solution phases as evidenced from UV-vis and EPR studies. All the complexes showed stability for almost 72 h in biologically relevant solutions. The reducing ability of the copper(II) complexes in the presence of ascorbic acid was analyzed by UV-vis and cyclic voltammetry techniques, which indicates the reduction of the copper(II) to a copper(I) center, and possible interaction within the cells. An in vitro antiproliferative study revealed the nontoxic nature of complexes to normal human dermal fibroblast (NHDF) up to a concentration of 100 ng/mL. The antiproliferative activity of the complexes was tested against three cancerous (human breast adenocarcinoma (MCF-7), hepatoma (HepG2), and lung (A549)) cell lines using MTT reduction assay, which showed enhanced activity for complexes 4 and 8 containing the hydrophobic substituent. Apoptotic and cellular uptake studies showed that complex 8 is readily taken up by HepG2 cell lines and induces ROS-mediated mitochondrial and caspase-dependent apoptosis. In silico studies indicated hydrogen bonding, hydrophobic, and pi-pair (pi-pi, pi-sigma, and pi-cation) interactions between the complexes and EGFR/VEGFR2 kinase receptors.
