ChemInform Abstract
Solid complexes of Fe(NO3)3 and Cu(NO3)2 with gaseous N2O4 prove to be efficient agents for the nitration of phenol and 4-substituted phenols. In comparison with other metal nitrates high rate, yield, and regioselectivity enhancements are observed. The selectivity for the formation of mono- or dinitration products can be easily controlled by changing the nature of the solvent and reaction temperature.
