Selective intramolecular C—H amination via metalloradical activation of azides: synthesis of 1,3-diamines under neutral and nonoxidative conditions. One aspect of the present invention is the synthesis of 1,3-diamines by intramolecular C—H amination of sulfamoyl azides. More specifically, sulfamoyl azides may be selectively aminated via metalloradical activation of azides, preferably with Co(II) porphyrins. In a particularly preferred embodiment, the Co(II) porphyrin is a D
