Heteroatom-doped porous carbon materials have exhibited promising applications in various fields. In this work, sulfur, nitrogen co-doped carbon materials (SNCs) with abundant pore structure were prepared by pyrolysis of sulfur, nitrogen-containing porous organic polymers (POPs) mixed with nano-CaCO3 at high temperature. Among the resultant materials, SNC-Ca-850 possesses a relatively high level of doped heteroatoms and exhibits an excellent catalytic performance for the selective oxidation of benzylic C-H bonds. It is noteworthy that nano-CaCO3 increases the doped sulfur content in the synthesized carbon materials to a large extent and impacts the existence modes of sulfur. In addition, it enhances the porous structure and specific surface area of the resultant SNCs significantly. This work provides a viable strategy to promote the doping of sulfur into carbon materials during the pyrolysis process.

The mode of asymmetric induction in an enantioselective intramolecular allylic substitution reaction catalyzed by a combination of palladium and a chiral phosphoric acid was investigated by a combined experimental and statistical modeling approach. Experiments to probe nonlinear effects, the reactivity of deuterium-labeled substrates, and control experiments revealed that nucleophilic attack to the pi-allylpalladium intermediate is the enantio-determining step, in which the chiral phosphate anion is involved in stereoinduction. Using multivariable linear regression analysis, we determined that multiple noncovalent interactions with the chiral environment of the phosphate anion are integral to enantiocontrol in the transition state. The synthetic protocol to form chiral pyrrolidines was further applied to the asymmetric construction of C-O bonds at fully substituted carbon centers in the synthesis of chiral 2,2-disubstituted benzomorpholines.

The coupling of aromatic electrophiles (aryl halides, aryl ethers, aryl acids, aryl nitriles etc.) with nucleophiles is a core methodology for the synthesis of aryl compounds. Transformations of aryl ketones in an analogous manner via carbon-carbon bond activation could greatly expand the toolbox for the synthesis of aryl compounds due to the abundance of aryl ketones. An exploratory study of this approach is typically based on carbon-carbon cleavage triggered by ring-strain release and chelation assistance, and the products are also limited to a specific structural motif. Here we report a ligand-promoted beta-carbon elimination strategy to activate the carbon-carbon bonds, which results in a range of transformations of aryl ketones, leading to useful aryl borates, and also to biaryls, aryl nitriles, and aryl alkenes. The use of a pyridine-oxazoline ligand is crucial for this catalytic transformation. A gram-scale borylation reaction of an aryl ketone via a simple one-pot operation is reported. The potential utility of this strategy is also demonstrated by the late-stage diversification of drug molecules probenecid, adapalene, and desoxyestrone, the fragrance tonalid as well as the natural product apocynin.

CuMgAl layered double hydroxide compounds (CuMgAl-LDHs) have been synthesized, characterized and in-vestigated in the aerobic CDC reactions. The results indicated that NH3 center dot H2O coprecipitated CuMgAl LDH (N-CuMgAl-LDH) was able to efficiently accelerate the CDC reactions between the alpha-Csp(3)-H of N-aryltetrahy-droisoquinolines and nucleophiles. A wide scope of N-aryltetrahydroisoquinoline analogues and nucleophiles with different C-H bonds (C-sp3-H, C-sp2-H and Csp-H) could be tolerated by the N-CuMgAl-LDH system. Compared with the sample using Na2CO3 as the precipitant (C-CuMgAl-LDH), N-CuMgAl-LDH showed higher catalytic activity, which probably was due to its higher surface acidity. Dual function of redox and acidity for the N-CuMgAl-LDH catalyst has been observed in the CDC reaction. According to the obtained catalytic results, kinetic isotope effect experiment and XPS analysis, iminium ion was proposed as the key intermediate, made possible by the cycle of Cu2+ and Cu+ under the aerobic conditions.

The C=C double bond cleavage on tertiary enaminones, enabling the formation of a new C-CF3 bond, has been realized as a practical method for the synthesis of alpha-trifluoromethyl ketones with only the promotion of TBHP and ambient heating. Control experiments support that the reactions proceed via a featured free radical process. The deuterium labeling experiment employing D2O indicates that water participated in the product formation by donating the hydrogen atom for the newly generated alpha-C-H bond in the product.

A brick pavement, tramped by humans, is exposed to atmospheric elements, thus allowing cyanobacteria and algae to colonise. In this article, we report on the factors that contribute to the slipperiness of a brick pavement at the University of Venda in the Limpopo province of the South Africa. Samples were collected from brick surfaces either colonised by green algae (treated) or not (control). The samples were acid-digested and analysed for metals by Inductively Coupled Plasma Mass Spectrometry (ICP MS) in parts per billion (ppb). The treated bricks, with green algae, had average high metal contents (ppb): Al 9456.02, Ti 731.23, V 46.44, Cr 78.85, Mn 862.93, Fe 16295.18, Co 23.57, Ni 59.36, Cu 66.31, Zn 160.57, As 7.92, Se 10.45, Mo 6.74, Cd 5.19, Sn 4.65, Sb 2.31 and Pb 19.51. In contrast, control bricks had a low average of metal content (ppb) as follows: Al 2.99, Ti 0.28, V 4.04, Cr 1.42, Mn 4.29, Fe 20.89, Co 0.36, Ni 2.74, Cu 5.64, Zn 4.21, As 0.56, Se <3.00, Mo 0.88, Cd 0.01, Sn 1.05, Sb 0.04 and Pb 0.04. Other factors that promote algae colonisation include high solar radiation, neutral pH, nutrients, low electrical conductivity and total dissolved solids. The algae colonisation of brick pavement results in an unaesthetic sighting and a slippery surface that is hazardous to humans. Recommanded Product: 86-29-3.

A series of metal-free N-doped carbon nanotubes (NCNTs) are synthesized using melanin or protoporphyrin IX as the dopant via a pyrolysis process. Multiwalled carbon nanotubes with various diameters are employed as the support, and their performance is compared with those of graphene and carbon black. The content of doped graphitic N is effectively controlled by varying the heating rate during pyrolysis. The obtained metal-free catalysts are employed to catalyze the hydrogenation of various nitroarenes under mild reaction conditions (2 MPa of H-2, 120 degrees C). Efficient and selective hydrogenation of 14 nitroarenes is achieved over NCNTs with outer diameters of <= 20 nm synthesized via pyrolysis of melanin at 800 degrees C. Graphitic N in the as-prepared NCNTs is found to play a key role in efficient hydrogenation. Kinetic data reveal that a zero-order reaction occurs on the NCNTs, and the apparent activation energy of 4-nitrophenol hydrogenation is as low as 35.69 kJ mol(-1). Recycling experiments indicate that the NCNTs have good stability and recyclability for hydrogenation of 4-nitrophenol. (c) 2019 Elsevier Ltd. All rights reserved. Name: 1-(4-Nitrophenyl)ethanone.

A facile and general synthesis of 2,4,6-triaryl pyrimidines has been developed. It involves a one-pot [2+1+1+1+1] pseudo five-component annulation of one methyl ketone, two aldehydes and two NH4OAc catalyzed by TfOH. One C-C and four C-N bonds are formed during the oxidative annulation process. The reaction shows good tolerance of many important functional groups in air and produces only water as the coproduct, making this methodology a highly versatile alternative to the existing methods for structuring pyrimidine framework.

Thirty-eight chalcone derivatives bearing a chromen or benzo[f]chromen moiety were synthesized and evaluated for their anti-inflammatory and analgesic activities. Using an ear edema model, anti-inflammatory activities were observed for compounds 3a-3s (ear inflammation: 1.75-3.71 mg) and 4a-4s (ear inflammation: 1.71-4.94 mg). All compounds also displayed analgesic effects with inhibition values of 66.7-100% (3a-3s) and 96.2-100% (4a-4s). The 12 compounds that displayed excellent anti-inflammatory and analgesic effects were tested for their inhibitory activity against ovine COX-1 and COX-2. Six compounds bearing a chromen moiety were weak inhibitors of the COX-1 isozyme but showed moderate COX-2 isozyme inhibitory effects (IC(50)s from 0.37 mu M to 0.83 mu M) and COX-2 selectivity indexes (SI: 22.49-9.34). Those bearing a benzo[f]chromen moiety were more selective toward COX-2 than those bearing a chromen moiety with IC(50)s from 0.25 mu M to 0.43 mu M and COX-2 selectivity indexes from SI: 31.08 to 20.67.
