Abstract:
Azo coupling of fluorinated 1,3-diketones with 4-ethoxycarbonyl-1H-imidazole-5-diazonium chloride led to the formation of 4-hydroxy-4-polyfluoroalkyl-1,4-dihydroimidazo{[}5,1-c]{[}1,2,4]triazine s. According to the (1)H and (19)F NMR data, these compounds in solution give rise to ring-chain tautomerism via opening of the C(4)-N(5) bond, which is especially characteristic of dihydroimidazotriazines with a polyfluoroalkyl substituent longer than trifluoromethyl group.
