A number of nitriles and cyano compounds inhibited chlorination by Streptomyces aureofaciens. In most cases, this inhibition was enhanced by bromide. Methylene blue and p-amino-propiophenone reversed the inhibition to some extent.

Monomeric vanadium oxide species is created on the surface of hydrotalcite (V/HT), which acts as a reusable solid catalyst for the highly efficient dehydration of amides into the corresponding nitriles.

Aromatic aldehydes bearing electron-donating groups are easily converted into their respective nitriles using NH(2)OH.HCl and TiO(2) under microwave irradiation, while those bearing an electron-withdrawing group give the corresponding oximes.

some amide derivatives have been synthesized by the reaction of corresponding nitriles with potassium tert-butoxide as a nucleophilic oxygen source under ultrasonic irradiation. this new methodology provides good to excellent yields in short reaction times (15-90 min) at room temperature.

The [3+2] cycloaddition between various nitriles and sodium azide proceeds smoothly in the presence of zeolite and sulfated Zircona as effective catalyst and in the water and DMF/MeOH, to give the corresponding arylaminotetrazoles in good to high yields. The reaction most probably precedes through the in situ formation of a catalyst azide species, followed by a successive [3+2] cycloaddition wi...

5-Substituted-1H-tetrazoles were synthesized by the [3 + 2] cycloaddition of sodium azide with various nitriles in the presence of nickel zirconium phosphate (NiZrP) as an effective heterogeneous catalyst in dimethylsulfoxide at 120 °C. This method has the advantages of good to high yields, simple methodology and easy work-up. The catalyst can be recovered by centrifuging and reused with good y...

The synthesis of 2-substituted benzothiazoles has been described using ZnO-nanoparticles as a catalyst. condensation 2-aminothiophenol and aryl/alkyl nitriles resulted in the formation va...

The first method for the stereoconvergent cross-coupling of racemic α-halonitriles is described, specifically, nickel-catalyzed Negishi arylations and alkenylations that furnish an array of enantioenriched α-arylnitriles and allylic nitriles, respectively. Noteworthy features of this investigation include: the highly enantioselective synthesis of α-alkyl-α-aryl nitriles that bear secondary α-al...

Nitrile is a functional group that usually is transformed to amides or carboxylic acids under strong reaction conditions in acidic or basic media and high temperatures. Amides have also been prepared from nitriles at room temperature using strong oxidizing agents such as hydrogen peroxide or sodium superoxide in DMSO. On the other hand biocatalytic hydrolysis of nitriles mediated by nitrilase, ...

The one-step conversion of aliphatic carboxylic acids to the corresponding nitriles has been accomplished via the merger of visible light mediated photoredox and cyanobenziodoxolones (CBX) reagents. The reaction proceeded in high yields with natural and non-natural α-amino and α-oxy acids, affording a broad scope of nitriles with excellent tolerance of the substituents in the α position. The di...
