A New Approach for the Synthesis of N-Arylamides Starting from Benzonitriles

open access: yesChemistry Proceedings, 2021
N-Arylamides are a ubiquitous component of a broad range of natural products and biologically active compounds. In this paper, a new synthetic protocol for the preparation of N-arylamides was developed via the hypervalent iodine-mediated aza-Hofmann-type

Progress of Enantioselective Nitrile Biotransformations in Organic Synthesis

open access: yesCHIMIA, 2009
Recent progress of enantioselective biotransformations of nitriles including various functionalized nitriles, ?-hydroxy and ?-amino nitriles, oxirane- and aziridine-containing carbonitriles is summarized in this short review article.

NaY Zeolite: A Useful Catalyst for Nitrile Hydrolysis

open access: yesMolecules, 2000
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, while aliphatic nitriles do ...

para-Selective C-H amidation of simple arenes with nitriles [PDF]

open access: yes, 2015
A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred.

Comparison of C═C bond hydrogenation in C-4 unsaturated nitriles over Pt/alumina [PDF]

open access: yes, 2016
The hydrogenation of allyl cyanide (but-1-ene-4-nitrile, AC), trans- and cis-crotononitrile (E- and Z-but-2-ene nitrile, TCN and CCN), and methacrylonitrile (2-cyano-1-propene, MCN) were studied, both singly and competitively, over a Pt/alumina catalyst ...

Composés d'addition des halogénures de niobium(V) et de tantale(V): II. Stabilité relative des composés des chlorures avec quelques éthers, sulfures et nitriles

open access: yesCHIMIA, 1971
New NMR methods for the determination of relative stability constants are developed. These methods are used for the study of niobium(V) and tantalum(V) chlorides adducts with series of ethers, sulfides, and nitriles. The relative stabilities of nitriles

Nitrile-assistant eutectic electrolytes for cryogenic operation of lithium ion batteries at fast charges and discharges [PDF]

open access: yes, 2014
The charge/discharge characteristics of lithium ion batteries at low temperature (LT = -20 ??C) are enhanced by using ethylene carbonate (EC)-based electrolytes with the help of assistant solvents of nitriles. Conventional liquid electrolytes (e.g.
