Aryl nitrile oxide cycloaddition reactions in the presence of pinacol boronic acid ester

open access: yesBeilstein Journal of Organic Chemistry, 2012
An aryl substrate with dual functionality consisting of a nitrile oxide and a pinacolyl boronate ester was prepared by mild hypervalent iodine oxidation (diacetoxyiodobenzene) of the corresponding aldoxime, without decomposition of the boronate ...

Metal Catalysis Acting on Nitriles in Early Earth Hydrothermal Systems

open access: yesLife, 2023
Hydrothermal systems are areas in which heated fluids and organic molecules rush through basaltic material rich in metals and minerals. By studying malononitrile and acetonitrile, we examine the effects of metal and mineral nanoparticles on nitrile ...

Synthesis of Spiroisoxazolines by 1,3-Dipolar Cycloaddition

open access: yesMolecules, 1997
The cycloaddition of the chiral nitrile oxide 1 to 1-R-substituted 3,3-methylene-5,5-dimethyl-2-pyrrolidinones 2 (where R is H, n-butyl-, 1,1-dimethylethoxycarbonyl-, 1-methylethenyl- and acetyl-) proceeds regioselectively under the formation of ...

Elastomeric Core-Conductive Shell Slurry Additive Stabilizes High-Voltage NCM811 Cathodes via Mechanical-Electrical Dual Regulation. [PDF]

open access: yesAdv 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 ...

Rapid Metal -free Macromolecular Coupling via in situ Nitrile Oxide-Activated Alkene Cycloaddition. [PDF]

open access: yesJ Polym Sci A Polym Chem, 2014
Nitrile oxide 1,3 dipolar cycloaddition is a simple and powerful coupling methodology. However, the self-dimerization of nitrile oxides has prevented the widespread use of this strategy for macromolecular coupling.
