ESR spectra of new nitroxide radicals

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The following compounds have been synthesized: 6-tert-butyl, 6-tert-octyl-, 6-fluoro-, 5-nitro-, and 6- and 8-oxy derivatives of hydrogenated 2,2,4-trimethylquinoline, as well as a stable 4,4′-di-tert-butyl nitroxide.

  2. 2.

    Alkylization of 2,2,4-trimethyl-1,2-dihydro-1,2,3,4-tetrahydroquinoline and diphenylamine by isobutylene in the presence of ZnCl2 at 170°C largely proceeds through the para position.

  3. 3.

    The structures of these new amines have been checked through ESR and NMR spectra. Hfs constants for o-, p-, and m-protons, for the o- and p-CH3 group protons (hyperconjugation mechanism), and for the fluorine atom, of these new nitroxide radicals have been evaluated.
