A practical copper-catalyzed nitration of electron-rich arenes with trimethylsilyl chloride and guanidine nitrate is reported. A variety of nitrated products were generated in moderate to excellent yields (32–99%) at ambient temperature under acid-free, open-flask, and operationally simple conditions.
