“…C1 has generally been used for these studies, because it can be produced easily in a nuclear reactor. Also some work has been done with recoil atoms [5,12,13]. The best investigated aromatic Compounds are the liquid chlorobenzenes and in particular CeHsCl: the chlorine atoms in the molecules serve as the source of ^^""Cl and C1 atoms.…”

The reactions of recoil " C1 atoms (produced in a high flux nuclear reactor) with liquid chlorobenzenes were investigated. The yields of " CI-for-H and Q-replacement reactions, of inorganic Compounds and of polymers were measured in the presence of scavengers, by GLCtechniques and by gelfiltration over Sephadex. In unscavenged chlorobenzene, C^ Hj" C1 (52%) is formed via a direct hot replacement reaction (5%), via a thermal exchange reaction (28%) and via a radiation induced exchange reaction (19%). It is believed that hot H-abstraction leads to the inorganic yield, because this yield is not influenced by the addition of organic unsaturated Compounds. The total organic yield is not in-fluenced by the addition of organic scavengers, but the natura of the products depends considerably on the kind of scavenger used.Ophthalmie Research Institute (lOI)

“…The results from the 34m Cl experiments given in Table 1 were preformed using an electron-beam of an average intensity of about 45 μΑ and an irradiation time of 15 min. When higher currents were reached in our facility, the organic yields for o-C 6 H 4 C1NH 2 were determined as a function of the irradiation time: 12.9% (1 min), 12.2% (2 min), 11.6% (5 min), 10.3% (10min) and 9.4% (20min). Neither an increase of the dose nor an increase of the temperature of the samples during the irradiations have an outspoken effect on the total organic yield.…”

“…The very high reactivity of aniline in the thermal zone was attributed to fast Η abstraction by thermal 38 CI atoms. BRINKMAN et al reported that 4 mol % aniline added to chlorobenzenes decreased the organic yield from 64% to 31% in case of recoil 3 8 CI atoms, but hardly any effect was found in the case of recoil 34m Cl atoms [10,11].…”

Reactions of Recoil CI Atoms with Chloroanilines

Reactions of recoil 34m Cl and 3, C1 atoms with o-and m-C 6 H, CINHJ result under high dose conditions in a total organic yield of about 15%, much lower than reported for all other substituted benzenes. The Cl-for-Cl substitution yield is about 5%, which means that thermal ipso addition -a major reaction channel for other chlorobenzenes -does not take place. The yield of polymers is about 3%, almost a factor of ten lower than for other arenes. It is supposed that Η abstraction from the NH 2 group by thermal and energetic CI atoms is the major process.

Hot atoms /Recoil chlorineAbstract By means of a simple model, involving reaction cross-section Parameters referring to the formation of individual products rather than to total yields, it is shown that in binary systems containing chiorobenzene, and an aliphatic component, the three labelled dichlorobenzenes are formed in one-stage reactions at the end of the recoil track, both with and without iodine scavenger present. It is suggested that iodine is involved in the cage processes.
