Advances in nitrile oxides chemistry

Experientia, 1970
Dopo 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 ...

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.

Ion–molecule reactions between ionized nitrile oxides and neutral nitrile

International Journal of Mass Spectrometry, 2002
Abstract The ion–molecule reactions of ionized nitrile oxide, RCN + O , with several neutral nitriles have been studied using both tandem mass spectrometric techniques and ab initio molecular orbital calculations. Ionized oxygen atom transfer as well as a formal substitution of nitric oxide by the neutral reagent in the radical cation were the ...

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.

Behaviour of nitrile oxides towards nucleophiles. Part III. Dimerisation of aromatic nitrile oxides catalysed by trimethylamine

Journal of the Chemical Society, Perkin Transactions 1, 1976
Reactions of aromatic nitrile oxides (1) with trimethylamine in ethanol give the dimers (2)(3,5-diaryl-1,2,4-oxadiazole 4-oxides) among other products. Kinetic measurements of reaction rates show that the dimerisations are, at low trimethylamine concentrations, first order in both nitrile oxide and nucleophile; rate constants are much lower than those ...
