Copper-Catalyzed Three- Five- or Seven-Component Coupling Reactions: The Selective Synthesis of Cyanomethylamines, N,N-Bis(Cyanomethyl)Amines and N,N'-Bis(Cyanomethyl)Methylenediamines Based on a Strecker-Type Synthesis

Molecules, 2013
We have demonstrated that a cooperative catalytic system comprised of CuCl and Cu(OTf)2 could be used to effectively catalyse the three-, five- and seven-component coupling reactions of aliphatic or aromatic amines, formaldehyde, and trimethylsilyl ...

Comparative innate responses of the aphid parasitoid Diaeretiella rapae to alkenyl glucosinolate derived isothiocyanates, nitriles and epithionitriles

, 2008
Cruciferous plants (Brassicaceae) are characterized by the accumulation of a group of secondary metabolites known as glucosinolates that, following attack by pathogens or herbivores, may be hydrolyzed to one of a number of products including ...

Triflic Anhydride Promoted Synthesis of Primary Amides and their Conversion into Nitriles

SynOpen, 2018
A facile, two-pot conversion of carboxylic acids into the corresponding nitriles has been developed using triflic anhydride as a promoter and aqueous NH4OH as a source of nitrogen.

Nickel-Catalyzed Reductive Arylation of Redox Active Esters for the Synthesis of α-Aryl Nitriles – Role of a Chlorosilane Additive [PDF]

, 2021
A nickel-catalyzed reductive cross-coupling of redox-active N-hydroxyphthalimide (NHP) esters and iodoarenes for the synthesis of α-aryl nitriles is described. The NHP ester substrate is derived from cyanoacetic acid, which allows for a modular synthesis

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

Beilstein 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.

A DFT Study on the Excited Electronic States of Cyanopolyynes: Benchmarks and Applications

Molecules, 2022
Highly unsaturated chain molecules are interesting due to their potential application as nanowires and occurrence in interstellar space. Here, we focus on predicting the electronic spectra of polyynic nitriles HC2m+1N (m = 0–13) and dinitriles NC2n+2N (n

Electrosynthesis of nitriles from primary alcohols and ammonia on Ni catalyst [PDF]

Despite the increasing interest on electrocatalytic refinery of renewable feedstocks to produce value-added chemicals, nitrile electrosynthesis from alcohols is rarely studied. Here, we report the direct electrosynthesis of nitriles from primary alcohols

Pd-Catalyzed α-Arylation of Nitriles and Esters and γ-Arylation of Unsaturated Nitriles with TMPZnCl·LiCl

, 2016
Using TMPZnCl·LiCl as a kinetically highly active base, nitriles and esters undergo a Pd-catalyzed α-arylation under mild conditions. Remarkably, in the case of α,β- or β,γ-unsaturated nitriles, a regioselective γ-arylation or a γ-alkenylation is ...
