Abstract: A number of new nitroxyadamantanes have been synthesized by nitroxylation of the corresponding substrates with nitric acid in acetic anhydride. High electrophilicity and reduced acidity of the system HNO3–Ac2O increases the stability of nitrates and significantly decreases the probability of formation of alcohols. In some cases, nitrolysis and oxidation of functional groups in the substrate are observed.
Ozone-mediated nitration of adamantane and derivatives with nitrogen dioxide: Selectivity in the hydrogen abstraction by nitrogen trioxide and subsequent coupling of the resulting carbon radicals with nitrogen dioxide

In the presence of ozone at -78°C, nitrogen dioxide reacts rapidly and selectively with adamantane at a bridgehead position to give the corresponding nitro derivative as the sole major product. The relative reactivity has been determined for a series of 1-substituted adamantanes, which reveals that electron-withdrawing substituents exert a considerable influence on the ease of substitution at the γ-position as well as the distribution of the N- and O-functionalized products. The results may be rationalized in terms of the initial hydrogen abstraction by nitrogen trioxide, followed by rapid trapping of the resulting adamantyl radicals with nitrogen dioxide.
