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.

Fragmentation of nitrile oxides with triethylamine

Tetrahedron Letters, 1983
Abstract 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.
