mixtures with acetic acid, aceticanhydride, and methylene chloride has been studied. More reactive substrates react with lowest selectivity regardless of the reaction medium. The primary nitroxylation products of cage hydrocarbons are nitrooxy derivatives. The compositions of reaction mixtures obtained in the reactions of some cage hydrocarbons with nitric anhydride in carbon tetrachloride have been determined

Transformations of 3,6-dehydrohomoadamantane (1) and 1,3-dehydroadamantane (2) with nitronium reagents were studied. In the case of compound 1 an oxidative route of reaction is realized resulting in addition of two nucleophiles from reagent or solvent to the strained CC bond. Contrary to this, compound 2 in the same conditions undergoes an electrophilic addition reaction.

5-Dehydrobicyclo[3.3.1]nonane (3) like2 formed 1, 5-disubstituted bicyclo[3.3.1]nonanes in the course of oxidativeaddition. The scheme of backside oxidativeaddition to the propellanic C-C bond is proposed. MNDO-calculations of propellanes(1)–(3) were carried out and the protonation as a model process of electrophilicaddition was studied using energy/C-C…H+ distance relationships. It was concluded that the nonelectrophilic
