Реферат: A reaction of (tert-butyl-NNO-azoxy)acetonitrile with N,N-dimethylacetamide dimethylacetal afforded 2,4-bis(tert-butyl-NNO-azoxy)-3-methylpent-2-enedinitrile 9 as a main product. This compound cyclized on silica gel surface with the loss of isobutylene to give 6-amino-5-(tert-butyl-NNO-azoxy)-4-methylpyridazine-3-carbonitrile 2-oxide 10. On the contrary, the cyclization of dinitrile 9 in protic solvents resulted in quite different products: furan, 1,2,3-triazepine, and pyridazine derivatives were among them. These reactions are the first examples of intramolecular reactions of (tert-butyl-NNO-azoxy) and cyano groups. The structures of products under investigation were confirmed by X-ray diffraction analysis.
