Phenol Ring

Addition of nitrogen dioxide in the THF solutions of Cu(ii) complexes of N2O2type ligands, L1H2and L2H2resulted in the nitration at the 4-position of coordinated equatorial phenolate ring of the ligand frameworks. Spectroscopic evidence suggests that the reaction proceeds through a phenoxyl radical complex formation.
