The review discusses compiled data on the N-H bond dissociation energies of 108 aromatic amines of various structures. A brief description of experimental methods for their determination has been given, and the results obtained by different methods have been compared. Stabilization energies of structurally different aminyl radicals (Delta E (RS)) have been calculated, and this structural energy has been compared with Delta E (RS) of phenylaminyl and phenoxyl radicals. Values of D (N-H), D (O-H), and D (S-H) for a series of hybrid antioxidants (19 compounds) are reported. Bibliography: 42 references.
