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.

The Name is 2,2-Diphenylacetonitrile. Through research, I have a further understanding and discovery of 86-29-3.

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.

Synergistic palladium and enamine catalysis was explored to promote ketone addition to unactivated olefins. A secondary amine-based organocatalyst was identified as the optimal co-catalyst for the directed Pd-catalyzed alkene activation. Furthermore, asymmetric hydrocarbon functionalization of unactivated alkenes was also achieved with good to excellent yield (up to 96% yields) and stereoselectivity (up to 96% ee). This strategy presented an efficient approach to prepare alpha-branched ketone derivatives under mild conditions.

I found the field of Chemistry very interesting.

Unprecedented direct access to terminal enones via alpha-methylenation of aryl ketones to form C=C bond is achieved under visible-light conditions using methanol as one carbon source substrate and solvent as well. The reaction involves Cu@g-C3N4-catalysed in situ oxidation of methanol into formaldehyde followed by dehydrative cross aldol type reaction. Various aryl ketones react efficiently with MeOH, producing alpha,beta-unsaturated carbonyl compounds only in 4-8 h at room temperature in excellent yield (84-97%). Operational simplicity, wide substrate scope, ambient reaction conditions, visible-light photocatalysis and novel application of MeOH as methylene donor substrate are the salient features making the envisaged protocol mild, efficient and green alternative to the existing methods for synthesis of such fine chemicals.

Anilines are the most important fine chemicals that have been widely used as the intermediates of industrial products. Herein, a new series of nanostructured Mo-based catalysts were reported, such as MoOx/ZSM-5(25), MoOx/ZSM-5(50) and MoOx/SBA-15, which can serve as efficient catalysts in the hydrogenation of nitroarenes by using hydrogen as the reducing reagent to afford functionalized anilines. Those catalysts showed both excellent activity and high chemoselectivity of the nitro group even though other reducible groups (C-X, C=C, C=O and C equivalent to N) were exiting. This protocol constitutes an economically responsible pathway for the synthesis of anilines in high yields, good functional group compatibility and high chemselectivity.

Efficient and mild reaction conditions for Wacker-type oxidation of terminal olefins of less explored homoallyl alcohols to beta-hydroxy-methyl ketones have been developed by using a Pd(ii) catalyst and MnO(2)as a co-oxidant. The method involves mild reaction conditions and shows good functional group compatibility along with high regio- and chemoselectivity. While our earlier system of PdCl2/CrO3/HCl produced alpha,beta-unsaturated ketones from homoallyl alcohols, the present method provided orthogonally the beta-hydroxy-methyl ketones. No overoxidation or elimination of benzylic and/or beta-hydroxy groups was observed. The method could be extended to the oxidation of simple terminal olefins as well, to methyl ketones, displaying its versatility. An application to the regioselective synthesis of gingerol is demonstrated.
