The properties and structure of N-chloro-N-methoxy-4-nitrobenzamide [PDF]

, 2012
The XRD study of N-chloro-N-methoxy-4-nitrobenzamide revealed the high pyramidality degree of its amide nitrogen atom in O–N–Cl moiety. N-Chloro-N-methoxy-4-nitrobenzamide reacts with AcONa in MeCN selectively forming N-acetoxy-N-methoxy-4-nitrobenzamide,

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Effects of fenfluramine and sigma‐1‐dependent pharmacological and genetic modulation in a mouse kindling model

Epilepsia, EarlyView.
Abstract Objective Sigma‐1 is a chaperone protein that serves as a key homeostatic regulator, implicated in neuronal excitability and seizure control. Positive allosteric modulators offer a use‐dependent means to enhance Sigma‐1 activity, potentially with favorable tolerability compared to direct agonists.

Preparation of benzolactams by Pd(II)-catalyzed carbonylation of N-unprotected arylethylamines [PDF]

, 2014
An unprecedented NH2-directed Pd(II)-catalytic carbonylation of quaternary aromatic α -amino esters to yield 6-membered 10 benzolactams has been developed. The reaction shows a strong bias to 6-membered lactams over 5-membered ones.

A copper-catalyzed arylation of tryptamines for the direct synthesis of aryl pyrroloindolines [PDF]

, 2012
An operationally simple, copper-catalyzed arylation of N-tosyltryptamines provides direct access to C3-aryl pyrroloindolines. A range of electron-donating and electron-withdrawing substituents is tolerated on both the indole backbone and the aryl ...
