✦ Synopsis
~SN CIDNP effects observed during nitration of phenolic compounds with nitric and nitrous acid are comparable showing that nitrous acid is not only a catalyst during nitration with nitric acid but also a reactive intermediate. The ~SN CIDNP effects are generated in radical pairs formed during encounters of NO2 and arene radical cations or aroxyl radicals.The mechanism given is valid for arenes more reactive than toluene.
