Triphenylphosphine mediates a metal-free, intermolecular, reductive amination between nitroarenes and boronic acids at ambient temperature under visible-light irradiation without any photocatalyst. A wide range of nitroarenes underwent C-N coupling with aryl-/alkylboronic acids providing high yields.
