The efficient and original palladium-catalyzed amination of 5-Aryl-1, 2, 4-triazines and 1, 2, 4, 5-tetrazines is reported. This Buchwald–Hartwig type reaction leads to the formation of aminated heterocycles via methylsulfur release. The reaction is optimized and a wide range of amines is used to determine the scope and limitations of this methodology.
