Isolation of Salts of the Nitronium Ion

The Reactivity And Structure Of Nitrogen Dioxide

“…Numerous crystalline derivatives have also been prepared, including compounds of the anions CIO?, ESO?, HSO?, HS20?, S2O7-, S»0«, NO?, BF?, SnF|" PF?, AsF?, SbF?, and AuF? (see 157,265).…”

“…Covalently bound Cl 2 O 6 isomerizes into ionic ClO 2 + ClO 4 − in the solid state below −5 °C;101, 102 the related NO 2 ClO 4 is even ionic (NO 2 + ClO 4 − ) at room temperature 163. As discussed above such X‐OClO 3 (X=ClO 2 , NO 2 ) molecules are promising precursors for the ClO 4 radical.…”

Nitration of Ortho-Mononitrotoluene

“…It has since become the accepted aromatic nitration mechanism theory. Ingold and coworkers (6, 7,9,70,72) are largely responsible for the present acceptance of this theory.…”
