In a room temperature redox neutral direct C-H amidation of heteroarenes, easily accessible hydroxylamine derivatives have been employed as tunable nitrogen sources. These highly regioselective reactions were enabled by a visible-light-promoted single-electron transfer pathway without a directing group. A variety of heteroarenes, such as indoles, pyrroles, and furans, could go through this amidation with high yields (up to 98%).
