Oxidative reactions of nitriles—I
Tetrahedron, 1958Abstract Diphenyl-, cyclohexylphenyl- and methylphenyl-acetonitrile react with tert.-butyl hydroperoxide in the presence of cuprous ions at 80°. By this means, α-tert.-butylperoxydiphenyl-, α-tert.-butylperoxyphenylcyclohexyl- and α-tert.-butylperoxymethylphenyl-acetonitrile, respectively, were obtained in good to excellent yields.

Behaviour of nitrile oxides towards nucleophiles. Part 5. Polymerization of aromatic nitrile oxides
Journal of the Chemical Society, Perkin Transactions 1, 1979Aromatic nitrile oxides undergo polymerization by treatment with trimethylamine in dimethyl sulphoxide. Chain lengthehing occurs via the C–O bonds, as shown by the catalytic hydrogenation of such polymers to aroylamides. The apparent degree of polymerization ranges from 15 up to ca. 100 monomer units. These polymers are quite stable in the solid state,

Advances in nitrile oxides chemistry
Experientia, 1970Dopo una breve introduzione storica, viene dato un quadro delle attuali conoscenze sulla chimica degli ossidi di nitrili con particolare riguardo ai suoi piu recenti sviluppi. L'applicazione di metodi gia noti e l'introduzione di nuovi metodi di preparazione hanno portato alla cinquantina il numero dei nitrilossidi isolati, oltre a quelli numerosi ...

Activation of nitriles by hydrogen bonding in cycloadditions with nitrile oxides
Journal of Heterocyclic Chemistry, 1984AbstractThe dipolarophilic activity of aromatic nitriles in cycloaddition with benzonitrile oxides is remarkably enhanced by ortho‐acylamino substituents. The activation depends upon the solvent and can be ascribed to a hydrogen bond which assists cycloaddition.

Fragmentation of nitrile oxides with triethylamine
Tetrahedron Letters, 1983Abstract The formation of 1,2,4-oxadiazoles is frequently observed as a side reaction in cycl o additions with nitrile oxides generated in situ and follows from a fragmentation induced by Et3N. This latter is oxidized to N,N-diethylvinylamine, which is trapped as a cycloadduct.
