Progress of Enantioselective Nitrile Biotransformations in Organic Synthesis

CHIMIA, 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

Molecules, 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]

, 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]

, 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 ...

Soft-SAFT modeling of vapour liquid equilibria of nitriles and their mixtures [PDF]

, 2010
Nitriles are strong polar compounds showing a highly non-ideal behavior, which makes them challenging systems from a modeling point of view; in spite of this, accurate predictions for the vapor-liquid equilibria of these systems are needed, as some of ...

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

CHIMIA, 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

Isotopic Anomalies in Primitive Solar System Matter: Spin-state Dependent Fractionation of Nitrogen and Deuterium in Interstellar Clouds [PDF]

, 2012
Organic material found in meteorites and interplanetary dust particles is enriched in D and 15N. This is consistent with the idea that the functional groups carrying these isotopic anomalies, nitriles and amines, were formed by ion-molecule chemistry in ...
