Syntheses based on nitrile oxides

Russian Chemical Bulletin, 1993
Interaction of aromatic nitrile oxides with bis-trimethylsilylthiodiimide results in 2-amino-4-aryl-1,2,3,5-oxathiadiazoles, the first representatives of a new class of heterocyclic compounds.

Syntheses based on nitrile oxides. 1. Reaction of aromatic nitrile oxides with N-cyanimides

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1990
The reaction of trialkylaminocyanimides with aromatic nitrile oxides leads to trialkylamino-(3-aryl-1,2,4-oxadiazol-5-yl)imides, while the corresponding reactions with sulfylcyanimines and phosphincyanimides do not take place. Using x-ray structural analysis the principal structural features of the 1,2,4-oxadiazole products have been elucidated.

The nitrile oxide–isocyanate rearrangement

J. Chem. Soc., Perkin Trans. 1, 1985
The thermal rearrangement of 2,4,6-trimethylbenzonitrile N-oxide to the corresponding isocyanate has been investigated by double isotopic (2H and 18O) labelling and kinetic experiments. Rearrangement proceeds with exchange of oxygen atoms, and this exchange occurs exclusively between nitrile oxide molecules.

One‐pot synthesis of precise polyisoxazoles by click polymerization: Copper (I)‐catalyzed 1,3‐dipolar cycloaddition of nitrile oxides with alkynes

, 2013
This article reports a new one-pot method for polymer preparation, which involves double click chemistry. In one pot, two click reactions take place sequentially by adding the reactants step by step. The first click reaction is to produce the monomer for

Reaction of Nitrile Oxides with Masked o‐Benzoquinones; Synthesis of Highly Functionalized Isoxazolines

, 2013
Masked o-benzoquinones, on reaction with nitrile oxides generated in situ from the corresponding hydroxamoyl chlorides, provide [3+2] cycloaddition products or novel isoxazoline derivatives through an unprecedented rearrangement.

ChemInform Abstract: CATALYZED REARRANGEMENT OF NITRILE OXIDES INTO ISOCYANATES

Chemischer Informationsdienst, 1977
The simultaneous migration of two ligands makes the rearrangement of nitrile oxides (1) to isocyanates (2) one of the most interesting ones in organic chemistry. However, use of the thermal reaction (1) is severely limited by competing dimerization. The rearrangement proceeds in excellent yields with SO2 as catalyst. equation image
