The 1,3-dipolar cycloaddition reactions (DCs) of nitrile oxides (NOs) to alkenes and alkynes are useful methods for the synthesis of 2-isoxazolines and isoxazoles respectively, which are important classes of heterocyclic compounds in organic and ...

Polyfluorinated nitrile oxides
Chemistry of Heterocyclic Compounds, 1989(2+3)-Cycloaddition of polyfluorinated aliphatic nitrile oxides, generated in situ, to donor dipolarophiles takes place regioselectively to give the 5-substituted isoxazolines, and is limited by the donor and steric properties of the dipolarophiles.

Iterative Assembly of Nitrile Oxides and Ynamides: Synthesis of Isoxazoles and Pyrroles.
Journal of Organic Chemistry, 2019Described is an iterative assembly of nitrile oxides and ynamides for the synthesis of isoxazoles and pyrroles. The nitrile oxides could undergo Cu(I)-free cyclization with terminal ynamides for accessing isoxazoles, which could engage in another ...

A novel cross 1,3-dipolar cycloaddition between azomethine imines with in situ generated nitrile oxides has been developed. This is the first example of employing a reaction partner containing two heteroatoms in the [3+3] cycloaddition involving ...

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,
