Efficient N-nitrosation of amines, amides, and ureas, and also S-nitrosation of thiols were performed with dinitrogen tetroxide impregnated on activated charcoal (N2O4/charcoal) in CH 2Cl2 at room temperature. High selectivity was observed for N-nitrosation of dialkyl amines, N-alkylamides and N-alkylureas. Dealkylation and N-nitrosation of trialkylamines were also performed by this reagent.

Conversion of nitrite to nitric oxide at zinc via S-nitrosothiols

Nitrite is an important reservoir of nitric oxide activity in the plasma and cells. Using a biomimetic model, we demonstrate the conversion of zinc-bound nitrite in the tris(pyrazolyl)borate complex iPr2TpZn(NO 2) to the corresponding S-nitrosothiol RSNO and zinc thiolate iPr2TpZn-SR via reaction with thiols H-SR. Decomposition of the S-nitrosothiol formed releases nitric oxide gas.
Silica-acetate complex of N2O4: A heterogeneous reagent for the selective nitration of phenols and nitrosation of thiols
Iranpoor,Firouzabadi,Heydari
, p. 703 - 710 (2007/10/03)
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.
