Surprisingly, the cyclic 5-acylimino-2,5-dihydro-1,2,3-thiadiazoles were obtained. The formation of thiadiazoles in this reaction was explained by the higher ability of arylhydrazono-N-acylthioacetamide intermediates to be oxidized comparing to their precursors. The presence of pseudobicyclic aromatic structure in the reaction product was a main factor favoring the formation of 1,2,3-thiadiazole ring Доп.точки доступа: Bolgova, A. I.; Lugovik, K.
