Plastic-crystalline solid-state electrolytes: Ionic conductivity and orientational dynamics in nitrile mixtures [PDF]

J. Chem. Phys. 150 (2019) 244507, 2019
Many plastic crystals, molecular solids with long-range, center-of-mass crystalline order but dynamic disorder of the molecular orientations, are known to exhibit exceptionally high ionic conductivity. This makes them promising candidates for applications as solid-state electrolytes, e.g., in batteries.

Umpolung Synthesis of Pyridyl Ethers by BiV‐Mediated O‐Arylation of Pyridones

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
We demonstrate that sterically‐ and electronically‐diverse pyridyl ethers can be accessed via BiV‐mediated C−O coupling of 2‐ or 4‐pyridones with arylboronic acids. Use of a bismacyclic reagent not only confers modularity on our methodology, but also results in highly regioselective O‐arylation that is unprecedented for BiV.

Combined experimental and theoretical studies of regio- and stereoselectivity in reactions of β-isoxazolyl- and β-imidazolyl enamines with nitrile oxides

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 ...

Atmospheric oxidation of nitriles

, 1977
The reports of nitrile formation in actual and simulated auto emissions suggests a potential environmental hazard associated with the wide scale use of catalytic exhaust converters. Specifically, the atmospheric oxidation of nitriles is believed to occur via radical intermediates which can lead to both NO/sub x/ and CO production.

Inhibition of acyl‐CoA synthetase long‐chain isozymes decreases multiple myeloma cell proliferation and causes mitochondrial dysfunction

Molecular Oncology, EarlyView.
Triacsin C inhibition of the acyl‐CoA synthetase long chain (ACSL) family decreases multiple myeloma cell survival, proliferation, mitochondrial respiration, and membrane potential. Made with Biorender.com. Multiple myeloma (MM) is an incurable cancer of plasma cells with a 5‐year survival rate of 59%.

TOMM20 as a driver of cancer aggressiveness via oxidative phosphorylation, maintenance of a reduced state, and resistance to apoptosis

Molecular Oncology, EarlyView.
TOMM20 increases cancer aggressiveness by maintaining a reduced state with increased NADH and NADPH levels, oxidative phosphorylation (OXPHOS), and apoptosis resistance while reducing reactive oxygen species (ROS) levels. Conversely, CRISPR‐Cas9 knockdown of TOMM20 alters these cancer‐aggressive traits.

A Survey of CH3CN and HC3N in Protoplanetary Disks [PDF]

, 2018
The organic content of protoplanetary disks sets the initial compositions of planets and comets, thereby influencing subsequent chemistry that is possible in nascent planetary systems. We present observations of the complex nitrile-bearing species CH3CN and HC3N towards the disks around the T Tauri stars AS 209, IM Lup, LkCa 15, and V4046 Sgr as well ...

The mechanism of pyridine hydrogenolysis on molybdenum-containing catalysts : III. Cracking, hydrocracking, dehydrogenation and disproportionation of pentylamine [PDF]

, 1974
The conversion of pentylamine on a MoO3-Al2O3 catalyst was studied between 250 and 350 °C, at various hydrogen pressures. The reactions observed were cracking to pentene and ammonia, hydrocracking to pentane and ammonia, dehydrogenation to pentanimine ...
