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

A convenient procedure was proposed for the synthesis of 4,4-dimethyladamantan-1-ol from 2-adamantanone. Esterification of the product with protected amino acid gave 1-[(2R, 3S)-N-benzoylphenyl-isoseryloxy]-4,4-dimethyladamantane.
A resin that includes a repeating unit shown by the following formula (10) has an excellent performance as a radiation sensitive acid generator, and exhibits only a small adverse effect on the environment and a human body.
wherein R1 represents a hydrogen atom or the like, M+ represents a specific cation, and n is an integer from 1 to 5.
