This Letter describes the development of a TiIII-mediated reaction for the C–H amination of arenes with hydroxylamine. This reaction is applied to a variety of electron-rich (hetero)arene substrates, including a series of natural products and pharmaceuticals. It offers the advantages of mild conditions (room temperature), fast reaction rates (<30 min), compatibility with ambient moisture and air, scalability
