The decomposition of 1-adamantyl chloroformate in acetonitrile, nitrobenzene, benzene, and isopropyl and tert-butyl alcohols in the presence of triphenylverdazyls as internal indicator was investigated preparatively and kinetically.In nitrobenzene small addition of water increase the reaction rate, and additions of tetraethylammonium halides reduce it.In isopropyl and tert-butyl alcohols and in nitrobenzene in the presence of tetraethylammonium halides the reaction rate depends on the nature of the substituent in the verdazyl.The reaction rate increases linearly with increase in the dielectric constant of the medium.It is assumed that an intimate ion pair is formed at the first stage of the reaction and undergoes fragmentation in the controlling stage to 1-adamantyl chloride or is converted into a solvent-separated ion pair.The latter reacts with the verdazyl or undergoes fragmentation to 1-adamantyl chloride.
