Ethylammonium nitrate (EAN)/Tf2O and EAN/TFAA: Ionic liquid based systems for aromatic nitration

experimental part, p. 8088 - 8094 (2011/11/13)
Acting as in situ sources of triflyl nitrate (TfONO2) and trifluoroacetyl nitrate (CF3COONO2), the EAN/Tf 2O and EAN/TFAA systems, generated via metathesis in the readily available ethylammonium nitrate (EAN) ionic liquid as solvent, are powerful electrophilic nitrating reagents for a wide variety of aromatic and heteroaromatic compounds. Comparative nitration experiments indicate that EAN/Tf2O is superior to EAN/TFAA for nitration of strongly deactivated systems. Both systems exhibit low substrate selectivity (K T/KB = 5-10) in (Figure presented) between values reported for covalent nitrates and preformed nitronium salts.
A mild one-pot procedure for the polynitration of activated arenes. Convenient preparation of dinitro- and trinitrodialkoxybenzenes
Nose,Suzuki
, p. 1539 - 1542 (2007/10/03)
When first treated with an excess of nitrogen dioxide alone and then in the presence of ozone at low temperature, dialkoxybenzenes are smoothly and stepwise polynitrated in a one-pot manner to afford the corresponding dinitro or trinitro derivatives in good yield.
