Nitrile Synthesis with Aldoxime Dehydratases: A Biocatalytic Platform with Applications in Asymmetric Synthesis, Bulk Chemicals, and Biorefineries

open access: yesMolecules, 2021
Nitriles comprise a broad group of chemicals that are currently being industrially produced and used in fine chemicals and pharmaceuticals, as well as in bulk applications, polymer chemistry, solvents, etc. Aldoxime dehydratases catalyze the cyanide-free

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.

Triphenylphosphine dibromide: A useful reagent for conversion of aldoximes into nitriles

open access: yesArabian Journal of Chemistry, 2015
A simple and convenient method for the synthesis of nitriles by dehydration of aldoximes has been developed using triphenylphosphine dibromide in acetonitrile at room temperature.

Optimized intermolecular potential for nitriles based on Anisotropic United Atoms model [PDF]

open access: yes, 2008
An extension of the Anisotropic United Atoms intermolecular potential model is proposed for nitriles. The electrostatic part of the intermolecular potential is calculated using atomic charges obtained by a simple Mulliken population analysis.

Oxidative 1,2-carboamination of alkenes with alkyl nitriles and amines toward γ-amino alkyl nitriles

open access: yesNature Communications, 2017
Difunctionalization of readily available alkenes is a powerful method to quickly build molecular complexity. Here the authors report a three-component, oxidative carboamination between alkenes, alkyl nitriles and amines, producingγ-amino alkyl nitriles.

An unprecedented palladium-arsenic catalytic cycle for nitriles hydration

open access: yesFrontiers in Chemistry, 2023
An unprecedented palladium/arsenic-based catalytic cycle for the hydration of nitriles to the corresponding amides is here described. It occurs in exceptionally mild conditions such as neutral pH and moderate temperature (60°C).

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

open access: yes, 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 ...

Efficient approach for the computational study of alcohol and nitrile adsorption in H-ZSM-5 [PDF]

open access: yes, 2012
Since many industrially important processes start with the adsorption of guest molecules inside the pores of an acidic zeolite catalyst, a proper estimate of the adsorption enthalpy is of paramount importance.

B–N/B–H Transborylation: borane-catalysed nitrile hydroboration

open access: yesBeilstein Journal of Organic Chemistry, 2022
The reduction of nitriles to primary amines is a useful transformation in organic synthesis, however, it often relies upon stoichiometric reagents or transition-metal catalysis.

Micellar electrokinetic capillary chromatography—Synchronous monitoring of substrate and products in the myrosinase catalysed hydrolysis of glucosinolates [PDF]

open access: yes, 2006
A micellar electrokinetic capillary chromatography (MECC) method has been developed for monitoring the myrosinase catalysed hydrolysis of 2-hydroxy substituted glucosinolates and the simultaneous formation of the corresponding degradation products ...
