Hitherto, certain metal nitrates were used as nitrating reagents for aromatic compounds. In this work Zr(NO3)(4)-GIC was used as nitrating reagent for toluene and phenol in different solvents to give the nitro products in various yields. The reaction products were separated and identified by gas chromatography. The GICs were examined by X-ray diffraction and thermogravimetric analysis. Depending on the solvent, the Zr(NO3)(4)-GIC showed a different reactivity towards the aromatic compounds.
