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

open access: yesMolecules, 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 ...

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

open access: yesSynOpen, 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.

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.

Unsaturated Nitriles:  Stereoselective MgO Eliminations

open access: yes, 2016
α,β-Unsaturated nitriles are readily synthesized by eliminating MgO from β-hydroxynitriles. Deprotonating acyclic, and cyclic, β-hydroxynitriles with excess MeMgCl smoothly generates dianion intermediates that eject MgO with concurrent formation of α,β ...

Nickel-Catalyzed Reductive Cyanation of Aryl Halides and Epoxides with Cyanogen Bromide

open access: yesMolecules
Nitriles are valuable compounds because they have widespread applications in organic chemistry. This report details the nickel-catalyzed reductive cyanation of aryl halides and epoxides with cyanogen bromide for the synthesis of nitriles.

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

open access: yesMolecules, 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

Preparation of unsaturated nitriles

open access: yes, 1983
The yield and the rate of formation of nitriles X-CH=CH-CN and 3- and 4-substituted nitriles X-C6H5CN (X = CH3; OR; SR; COOCH3) were investigated in the reaction of vinyl and aryl bromides with CN(-), under catalysis with Pd0 and macrocyclic polyethers ...

Metalated Nitriles:  Cation-Controlled Cyclizations

open access: yes, 2016
Judicious choice of cation allows the selective cyclization of substituted γ-hydroxynitriles to trans- or cis-decalins and trans- or cis-bicyclo[5.4.0]undecanes.
