| Popis: | Free radicals in the heat-treated barbituric acid derivatives were studied by epr spectroscopy. The radicals were identified in alloxan, uramil, violuric acid, dilituric acid, and cyclobarbital. Three types of decomposition were observed: (a) loss of the substituent, (b) change in the substituent, and (c) scission of the ring. The CO- NH 2 fragments were positively identified in the decomposition process of alloxan and violuric acid. |
