Controllable cyanation of carbon-hydrogen bonds by zeolite crystals over manganese oxide catalyst
Nature Communications, 2017 Sustainable strategies for nitrile synthesis are needed. Here, the authors report an environmentally benign, selective heterogeneous catalyst for the synthesis of nitriles by the oxidative cyanation of carbon and hydrogen (C-H) bonds, which comprises ...

Site- and Regioselectivity of Nitrile Oxide-Allene Cycloadditions : DFT-Based Semiquantitative Predictions [PDF]
, 2017 Nitrile oxide 1,3-dipolar cycloaddition to arylsulfonyl- and dialkylaminoallenes have been investigated within the framework of the Kohn-Sham density functional theory (DFT) at the B3LYP/6-31G(d,p) level. The hitherto-unexplained experimental behavior of

Elastomeric Core-Conductive Shell Slurry Additive Stabilizes High-Voltage NCM811 Cathodes via Mechanical-Electrical Dual Regulation. [PDF]
Adv Sci (Weinh)A core‐shell ASA slurry additive constructs a mosaic‐like interface on high‐voltage NCM811 cathodes. This architecture decouples interfacial functions: the elastomeric core buffers mechanical stress to prevent microcracking, while the conductive shell facilitates rapid ion/electron transport, enabling mechanical‐electrical dual regulation and enhanced ...

Synthetic approaches to biologically active sulfonates and sulfonamides [PDF]
, 2010 This research describes the scope of 1,3-dipolar cycloaddition between selected 1,3-dipoles (nitrile oxide/nitrone) and dipolarophiles (PFP ethenesulfonate/PFP-1-bromoethenesulfonate). Nitrile oxide cycloaddition with PFP-1-bromoethenesulfonate furnished

Beilstein Journal of Organic Chemistry, 2016 Reactions of β-azolyl enamines and nitrile oxides were studied by both experimental and theoretical methods. (E)-β-(4-Nitroimidazol-5-yl), (5-nitroimidazol-4-yl) and isoxazol-5-yl enamines smoothly react regioselectively at room temperature in dioxane ...

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
