Pârvulescu,b,* a Faculty of Chemistry & Chemical Engineering, Chemistry Department, Babes-Bolyai WebThe reactions of OH radicals with SO 2, H 2 S, thiophenol, and a series of aliphatic thiols (1–5 C-atoms) have been investigated in 201 and 381 reaction chambers at 1 atm total pressure and 300 K using a competitive kinetic technique. Initially, OH radicals were produced by photolysis of CH 3 ONO/NO mixtures in air.

WebAug 21, 2024 · The resulting conjugates with thiophenol have capacity for the oxidation–elimination reaction by the action of ROS of a tumor cell with the release of initial cytotoxic lactones. It has been proposed to use the resulting sulfur-containing conjugates as ROS-activated prodrugs of sesquiterpene lactones. Oxidation. Thiophenols, especially in the presence of base are easily oxidized to diphenyl disulfide: 4 C 6 H 5 SH + O 2 → 2 C 6 H 5 S-SC 6 H 5 + 2 H 2 O. The disulfide can be reduced back the thiol using sodium borohydride followed by acidification. This redox reaction is also exploited in the use of C 6 H 5 SH as a … See more Thiophenol is an organosulfur compound with the formula C6H5SH, sometimes abbreviated as PhSH.
