Controllable cyanation of carbon-hydrogen bonds by zeolite crystals over manganese oxide catalyst

open access: yesNature 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 ...

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

open access: yesBeilstein 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 ...

Synthesis of a Novel Tetracyclic Isoxazole by Intramolecular Nitrile Oxide Cycloaddition

open access: yesMolbank
Intramolecular cycloadditions have the great advantage of forming two rings simultaneously. We report the use of intramolecular [3 + 2] cycloaddition of the nitrile oxide derived from an N-propargylbenzimidazole oxime in the synthesis of a hitherto ...

Synergistic Effects of Separator Architecture and Electrolyte Chemistry on the Electrochemical Stability of Lithium Ion Batteries With Li-Mn Rich Cathodes and µ-Si Anodes. [PDF]

open access: yesAdv Sci (Weinh)
This work reveals that synergistic engineering of separator architecture and electrolyte chemistry determines the long‐term stability of LMR||µ‐Si cell chemistry. The introduction of N, N‐dimethylsulfamoyl fluoride (DMFSA) as a co‐solvent with fluoroethylene carbonate (FEC) promotes robust interphases on both electrodes, effectively mitigates side ...
