N2O4 was easily impregnated on polyethyleneglycol to give a stable reagent. The polyethyleneglycol-N2O4 (PEG-N2O4) system was used as an effective nitrating agent for the nitration of phenols. Mono- and dinitrophenols can be obtained via direct nitration of phenols in the presence of PEG-N2O4 at room temperature in moderate to high yields. Copyright Taylor & Francis Group, LLC.

Dinitrophenols can be obtained via direct nitration of phenols with trichloroisocyanuric acid, NaNO2 and wet SiO2 at room temperature under solvent-free conditions with moderate to high yields.
Silica-acetate complex of N2O4: A heterogeneous reagent for the selective nitration of phenols and nitrosation of thiols

Complexation of gaseous N2O4 with acylated silica gel affords an addition compound, which is an efficient heterogeneous reagent for the selective mono- and dinitration of phenol, substituted phenols and nitrosation of thiols.
Silica-polyethyleneglycols/N2O4 complexes as heterogeneous nitrating and nitrosating agents
Iranpoor,Firouzabadi,Heydari
, p. 1027 - 1035 (2007/10/03)
Silica-chloride was reacted with different quantities of H(OCH2CH2)nOH (n = 2-4) to furnish silica-based linear polyethylene glycols and cyclic polyethylene glycolic ethers. The N2O4 complex of silica-tetraethylene glycolic ether (III) was selected and used as a stable, cheap, and heterogeneous silica-based reagent for the selective mono- and dinitration of phenols and nitrosation of thiols.
