Early events following radiolytic and photogeneration of radical cations in hydrocarbons

Trapping of radiolytic hydrogen by amorphous cobalt oxysulfide

“…The studies of hydrocarbons radiolysis have revealed a rich chemistry involving the initial ionic species produced [25]. Radiolysis of hydrocarbons occurs through formation of radical cations and their disappearance via ion-molecule reactions.…”

Selective Alkane Transformations via Radicals and Radical Cations: Insights into the Activation Step from Experiment and Theory

“…Irradiation of alkanes in matrixes is another way to hydrocarbon radical cations, which may be directly observed at low temperatures. [766][767][768][769] SET alkane activations often are more selective than electrophilic radical activations because one electron is removed from a HOMO with σ-character, and the ionized species thus obtained are denoted as σ-radical cations which possess a definitive structure in many cases. 770 As the electron is removed from a bonding orbital, the σ-radical cations have one or several partially broken (elongated) σ-bonds.…”

“…For sterically unhindered donors under photooxidations , or with charged oxidants an inner-sphere SET 137,758 is possible. Irradiation of alkanes in matrixes is another way to hydrocarbon radical cations, which may be directly observed at low temperatures. − …”

Mechanism of Organic Reactions Under the Effect of Radiolysis

“…The presence and type of scavengers affect on the radiation yield. Mechanisms of ion molecules and ion molecule radicals interpret the formation of many radiolytic products [13,14] Ter-butanol acts as 'OH scavenger in aqueous oxygenated system forming terbutanol peroxy radical [15] . The haloginated hydrocarbons scavenge electrons and the produced HX scavenge electrons too [16,17] .…”
