Abstract
It has been found that the condensation of 1-(1-arylimidazolin-2-yl)-3-arylurea derivatives with oxalyl chloride lead to formation of 1-aryl-5,6(1H)dioxo--2,3-dihydroimidazo[1,2-a]imidazole and 1,6-dihydro- 5,7(1H)dioxo-2,3-dihydroimidazo[1,2-a][1,3,5]triazine systems. Probable course of reaction is discussed.
