Abstract
Reactions of chlorocarbonyl isocyanate and chlorosulfonyl isocyanate with aminopyrazoles and active methylene nitriles are reported. They lead to novel pyrazolo[1,5-a]-1,3,5-triazines and barbituric acid derivatives. The structures of the products and the mechanisms of their formation are reported.
