Notes:
During the irradiation of phenol (1) with 15N-enriched tetranitromethane in acetonitrile, and during the reaction of 1 with 15N-enriched nitric acid and nitrous acid, emission due to the nitration products o- and p-nitrophenol (2a, 2b) is observed in the 15N-NMR spectra. The CIDNP effects are built up by radical pairs formed by the encounters of the radicals NO2· and 1+· or PhO·. During the reaction of 1 with nitrous acid, 2b is formed, in part due to a non-radical reaction, via oxidation of p-nitrosophenol (3).
