A novel non-acid methodology for the preparative nitration of aromatic compounds with the lower oxides of nitrogen using a combination of ozonized oxygen or air and some third substance as the promoter is described. The reaction, referred to as the kyodai-nitration, is now subject to industrially based research as the promising pollution-free and energy-saving substitute for the century-old, yet currently ongoing commercial process based on the use of nitric acid-sulfuric acid.
