Notes:
The methane chemical ionization mass spectra of 1-hydroxy-2-azaadamantane, its lactolactam, and 1-chloro-2-azaadamantanes exhibit high intensity dimeric species. These correspond to [2M+H]+ or stable fragments formed via gas phase chemical reactions, such as dehydration (aminol case) or dehydrohalogenation (chloroazaadamantanes). The tert-amino chloroazaadamantane forms a stable [2M+C2H5]+ ion with much higher intensity than the [2M+H]+ ion. Similar dimeric species were observed with simple functionalities, including amide, amine, alcohol and alkene. Pressure, temperature and, apparently, steric effects play important roles. Structures are proposed for the various dimeric ions.
