WebThese compounds were investigated as catalysts for the oxidation of thiophenol to diphenyl disulfide by using air as an oxidizing agent, both in cyclohexane and in an ionic liquid (1-butyl-1-methylpyrrolidinium bis (trifluoromethanesulfonyl)imide), at temperatures below 100 °C, affording high reaction rates (TON 34.8, with 100% conversion after 5 … WebThiols are generally amenable to gas chromatographic analysis, When thiophenol is analyzed by gas chromatography-mass spectrometry, however, its mass spectrum also …
Electrochemical Oxidative Esterification of Thiophenols: …
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. This foul-smelling colorless liquid is the simplest aromatic thiol.
