Several derivatives of mesoionic imidazopyrimidine-5,7-dione and 1,2,4-triazolopyrimidine-5,7-dione, two new examples of mesoionic xanthine ring systems, were prepared and characterized.These compounds were conveniently prepared by the condensation of bis-(2,4,6-trichlorophenyl) malonates with the appropriately substituted alkylaminoimidazole or 1,2,4-triazole.
