摘要：
Dinitroaromatics are valuable organic compounds. However, the high value of these compounds is accompanied by significant risks and formidable challenges. Herein, we report a safe and highly efficient method for the dinitration of various aromatic compounds, using KNO3 as nitrating agent, polyphosphoric acid as solvent and catalyst. This approach provides a safer and more efficient alternative to the traditional mixed acid system, making it suitable for a range of substrates, especially highly deactivated arenes.
