- Nitration of substituted phenols by different efficient heterogeneous systems
-
Nitration of substituted phenols were carried out by the mixture of sodium nitrite and wet SiO2 (50% w/w) in the presence of four different efficient heterogeneous systems: 1) oxalic acid dihydrate (I), 2) sodium hydrogen sulphate (II), 3) aluminum hydrogen sulphate (III) and 4) silica sulphuric acid (IV) in CH2Cl2 at room temperature and high yields. Optimum conditions for theses systems and the regioselectivities of the reactions are reported.

- Regio-selective mono nitration of phenols with ferric nitrate in room temperature ionic liquid
-
The mono nitration of phenols with ferric nitrate has been achieved in high regio-selectivities in 1-3 h at 30-60°C using the ionic liquid 1,3-di-n-butylimidazolium tetraflouroborate [bbim]BF4 as the solvent. In particular, excellent para selectives of the order of 76-86% for unsubstituted, ortho and meta-substituted phenols were observed.

- The nitration of electron-rich aromatics
-
The successful mononitration of a variety of electron-rich aromatic substrates is reported, employing either nitronium tetrafluoroborate or 'claycop' as the nitrating agent. Dinitration of four of the substrates was achieved when employing nitronium tetrafluoroborate. Several of the products have previously been prepared only by indirect methods.

- STUDIES ON THE TWO-PHASE NITRATION OF PHENOLS (part 2)
-
Gas phase Ionization Potentials can be correlated with solution Oxidation Potentials for phenols and used to predict the likelihood of successful nitration using the two-phase procedure.The interaction of steric and electronic effects then determines the sites of nitration by radical recombination of the phenoxy radical and NO2.Nitration of dioxybenzenes may give insights into the nitration mechanism.
