Pulse radiolysis of ethyl, n-propyl, n-butyl and n-amyl amine in aqueous solutions

C-N bond cleavage reactions on the radiolysis of amino-containing organic compounds and their derivatives in aqueous solutions

“….05 -radicals with the unpaired electron situated on a-carbon atom (Simic et al 1971, Getoff andSchworer 1973). The main pathway for the C-N bond cleavage on the radiolysis of aliphatic amines is hydrolysis of imines formed as a result of disproportionation of various aminoalkyl and aminyl radicals.…”

Distonic radical cations in gaseous and condensed phase

“…Optical absorption studies of the radicals generated by pulse radiolysis of aliphatic amines (319)(320)(321) and amino acids and small peptides (322) in acidic aqueous solution support that distonic amine ions are formed under these conditions. The mechanism whereby O H causes decarboxylation of amino acids (e.g., eq.…”

Hydrogen gas yields in irradiated room-temperature ionic liquids

“…The amino group generally enhances the rate of hydrogen abstraction from an adjacent C-H bond by H and OH radicals in aliphatic amines, but quaternization of the amino group removes the effect and favors C-H groups more distant from a C-H (Getoff and Schworer, 1973;Horspool, 1996). The aforementioned effect of quaternization may be at least partly responsible for the G(H 2 ) values of bmpyrr Tf 2 N and Et 3 NH Tf 2 N (Table 1) which might appear underestimated in the context of H 2 yields from irradiated aliphatic amines.…”
