The reactions of hydrogen atom with organosulfur compounds

Assessment of Damage of Glutathione by Glow Discharge Plasma at the Gas–Solution Interface through Raman Spectroscopy

“…It not only originated from the dissociation of water molecules, but also from the neutralization of aqueous electron by hydrogen ion in acid solution as in our experimental conditions (pH 3.1). [18,61] Littman et al have examined the products of aqueous phase reactions between hydrogen radical and cysteine and found that the cystine was the main product in acid or neutral solution. [62] The formation mechanism was explained satisfactorily by reaction (3).…”

Temperature dependent rate constant for the reaction of H‐atoms with carbonyl sulfide

“…The rate constant of reaction (6) is not well established. The available measurements of k 6 (between 1.1 × 10 −11 and 4.15 × 10 −11 cm 3 molecule −1 s −1 at room temperature) have been reviewed by Safarik and Strausz 16 who recommended a “best value” for k 6 = 2.5 × 10 −11 cm 3 molecule −1 s −1 . Although the secondary reaction is quite fast, its effect on the measurements of k 1 can be considered as negligible due to low initial concentrations of H atoms used.…”

Photochemically Triggered Alkylthiol Reactions on Highly Ordered Pyrolytic Graphite

“…Hence we exclude the possibility that the high coverage layers observed with MUA are the result of thiyl radical addition to the graphite surface. On the other hand, it has been demonstrated that RSH molecules undergo RSH cleavage leading to the formation of alkyl radicals under reductive attack by either solvated electrons , or hydrogen atoms − according to the following reactions: normalH• + RSH → normalR• + normalH 2 normalS normale − + RSH → normalR• + HS − …”
