Charvet, Sylvain;Medebielle, Maurice;Vantourout, Julien C. research published 《 Mn-Mediated α-Radical Addition of Carbonyls to Olefins: Systematic Study, Scope, and Electrocatalysis》, the research content is summarized as follows. A systematic study of the manganese-mediated α-radical addition of carbonyl groups to olefins is presented. After an in-depth investigation of the parameters that govern the reaction, a first round of optimization allowed the development of a unified stoichiometric set of conditions, which were subsequently assessed during the exploration of the scope. Due to observed limitations, the knowledge accumulated during the initial study was reengaged to quickly optimize promising substrates that were so far inaccessible under previously reported conditions. Altogether these results led to the creation of a predictive model based on the pKa of the carbonyl compound and both the substitution and geometry of the alkene coupling partner. Finally, a departure from the use of stoichiometric manganese was enabled through the development of a robust and practical electrocatalytic version of the reaction.

Chen, Huan;Rhoades, Charles C.;Chow, Alex T. research published 《 Characteristics of soil organic matter 14 years after a wildfire: A pyrolysis-gas-chromatography mass spectrometry (Py-GC-MS) study》, the research content is summarized as follows. Severe wildfires combust most above ground vegetation and detritus layers, altering the content and chem. composition of soil organic matter (SOM). To evaluate the lasting effects of wildfire on SOM and the recovery of burned soils, we sampled surface (Oa horizon) and mineral soils (0-5 and 5-15 cm depths) in unburned areas and areas burned at moderate and high severity 14 years after the 2002 Hayman Fire, in Colorado, USA. We characterized SOM using Pyrolysis Gas Chromatog. Mass Spectrometry (Py-GC-MS) and identified 106 pyrolyzates within eight chem. classes [aromatic hydrocarbon (ArH), carbohydrate (Carb), lignin compound (LgC), nitrogen containing compound (Ntg), polyaromatic hydrocarbon (PAH), phenol compound (PhC), saturated hydrocarbon (SaH), and unsaturated hydrocarbon (UnSaH)]. Burned soils had greater total quantified peak areas (TQPA) for the pyrogenic C indicator (PyC) benzene, compared to unburned soils; however, other common PyC markers were not abundant in burned relative to unburned soils. Factor anal. on the individual pyrolyzates suggests that factors 1 and 2 correlated with pyrolyzate aromaticity and hydrophobicity, resp. Sample factor scores potentially suggest that SOM aromaticity increases with fire severity, though difference between moderate and high severity was slight. Factor anal. also indicates that the ratio of [ArH + Ntg] / [PhC + LgC] may serve as index of PyC content in SOM. This study shows that wildfire effects on SOM character may persist for more than a decade of ecosystem recovery and that Py-GC-MS coupled with factor anal. has utility for evaluating how disturbance alters SOM and PyC in complex environments.

Abe, Takumi;Noda, Kenta;Sawada, Daisuke research published 《 Synthesis of α-substituted indolylacetamide using acetonitriles as acetamide enolate equivalents through O-transfer reactions》, the research content is summarized as follows. Authors introduce readily available ammonium hemiaminals as O-transfer reagents and com. available acetonitriles as a primary amide enolate precursor. The combination serves as an amide enolate equivalent, thereby providing one-pot access to α-substituted indolylacetamides I (EWG = COOMe, SO₂Me, C(O)Ph, etc.; R¹ = H, Ph). A broad substrate scope and good functional group tolerance as well as gram-scale synthesis make this protocol highly attractive. Mechanistic experiments suggest that the cyano group is trapped by a hydroxy group of hemiaminals en route to the desired primary amides under metal-free conditions.

The existence of off-cycle catalyst cooperativity in amine/metal combined catalysis was disclosed. The exptl. and d. functional theory study of the amine/metal co-catalyzed enantioselective Michael/carbocyclization cascade reaction between allenes and α,β-unsaturated aldehydes revealed that the dual catalysts can perform off-cycle cooperativity that gives access to stable bicyclo[3.2.0]heptane species that limits the carbocycle product formation. Insight into this mode of co-catalyst cooperativity sheds new light on the chiral amine/metal co-catalyzed reactions of to date and gives deeper understanding for improved future design of this type of enantioselective reactions.

Alepee, Nathalie;Leblanc, Virginie;Grandidier, Marie-Helene;Teluob, Severine;Tagliati, Valerie;Adriaens, Els;Michaut, Valerie research published 《 Development of the SkinEthic HCE Time-to-Toxicity test method for identifying liquid chemicals not requiring classification and labelling and liquids inducing serious eye damage and eye irritation》, the research content is summarized as follows. This study describes the development of a Time-to-Toxicity approach for liquids (TTL) based on the SkinEthic HCE tissue construct, capable to distinguish chems. that do not require classification for serious eye damage/eye irritation (No Cat.) from chems. that require classification for eye irritation (Cat. 2), and serious eye damage (Cat. 1). Briefly, the Time-to-Toxicity of 56 liquids was evaluated by exposing SkinEthic HCE tissue constructs to the test chem. for three different time periods (5-min, 16-min, and 120-min). Based on the viability observed for the different exposure periods, a classification was assigned. The within laboratory reproducibility in terms of concordance in classifications (3 UN GHS categories), based on a set of 50 liquids, was 80.0%. Furthermore, 84.3% Cat. 1 (N = 17), 79.4% Cat. 2 (N = 21) and 72.2% No Cat.(N = 18) were correctly identified with the SkinEthic HCE TTL test method. This study provides evidence that the SkinEthic HCE Time-to-Toxicity method (multiple exposure times) is capable of distinguishing Cat. 2 liquids from Cat. 1 liquids This is an advantage compared to the SkinEthic HCE EITL method (single exposure time) that can distinguish No Cat. chems. from chems. that do require classification and labeling for eye irritation/serious eye damage (Cat. 2/Cat. 1).

Aljaddua, Huda I.;Alhumaimess, Mosaed S.;Hassan, Hassan M. A. research published 《 CaO nanoparticles incorporated metal organic framework (NH₂-MIL-101) for Knoevenagel condensation reaction》, the research content is summarized as follows. Porous materials based on NH₂-MIL-101(Cr) MOF and their hierarchical acid-base composite with non-precious CaO was successfully prepared using a one-pot scalable hydrothermal approach. The composites were characterized by XRD, FTIR, UV-vis, 1HNMR, TGA, N₂ adsorption-desorption isotherms, HRTEM and FESEM. The quant. assessment of the basic sites was performed by benzoic acid titration The results reveal that there is no remarkable structural alterations in the NH₂-MIL-101(Cr) after incorporation of CaO. Raising the CaO content boosted the strength of and content of Lewis basic sites from 0.31 to 1.34 mmol g^-1 due to the incorporation with CaO (0.04). Knoevenagel condensation reactions were performed as the probe reactions over the CaO/NH₂-MIL-101(Cr) catalysts. Both basic and acidic sites potentially boosted the reaction. Pure NH₂-MIL-101(Cr) display the catalytic conversion in the reaction (11%) which could be attributed weak basic sites on the NH₂-MIL-101(Cr) framework. However, the conversion (%) was potentially increased over NH₂-MIL-101(Cr) loaded with various content of CaO. The highest performance of (99%) conversion was achieved for (0.04) CaO/NH₂-MIL-101(Cr) catalyst. Exceptional conversion above 90% have been obtained for benzaldehyde derivatives both withdrawing and donating electron moieties. The composites can be recycled in four runs with a very small loss in performance. Furthermore, the composites produced tend to be feasible for various catalytic processes, exploring new avenues to produce of novel inorganic and organic composite materials as heterogeneous catalysts.
