Reactivity of polycyclic aromatic hydrocarbons toward nitrating species
The transformation rates of 25 polycyclic aromatic hydrocarbons (PAH) and 4 derivatives of anthracene are investigated in dilute solutions containing dinitrogen tetraoxide and nitric and nitrous acid under conditions which are relevant for determining the relative reactivities of PAH and their derivatives toward nitrogen compounds in the atmosphere. The reactivities of some of the PAH are several orders of magnitude higher than that of benzene. The reactions are apparently electrophilic, as electron-donating substituents, e.g., methyl, enhance the reactivity of anthracenes, and electron-withdrawing substituents, e.g., nitro, diminish it. The reactivities of PAH correlate with spectroscopical constants, and it seems possible to relate the differences in reactivity to differences in the chemical structure. A classification of the reactivity of PAH in electrophilic reactions in the environment under dark and weak lighting conditions is set up. 60 references.
