A one-pot procedure has been proposed for the synthesis of amines directly from cage hydrocarbons. A number of cage amines have been synthesized by treatment of adamantane, its homologs, and structurally related cage hydrocarbons with nitric acid in acetic acid and subsequent addition of urea and heating.

An efficient one-pot procedure has been developed for the synthesis of cagealcohols with hydroxy groups in the bridgehead positions. The procedure includes initial nitroxylation with nitric acid or a mixture of nitric acid with acetic acid and subsequent hydrolysis in the presence of urea.

Abstract Reactions of alcohols of the adamantane series and adamantan-1-yl nitrates with sulfur nucleophiles in 94% sulfuric acid afforded a number of new sulfur-containing adamantane derivatives such as carbamothioates, isothiocyanates, and carbamodithioates. Di(adamantan-1-yl) disulfide was synthesized by reaction of admantan-1-yl nitrate with sodium sulfide nonahydrate in 94% sulfuric acid.
