The electrochemical oxidative cross‐dehydrogenative coupling of arylsulfinic acids with thiophenols was achieved via a radical process. A wide range of arylsulfinic acids and substituted thiophenols were found to be tolerated, providing unsymmetrical thiosulfonates in good to excellent yields. This electrochemical method can also be used for the reaction … WebJan 20, 2024 · In this context, we note a recent study by Marchetti et al. on near ultraviolet spectroscopy and the photodissociation dynamics of 2- and 3-substituted thiophenols. There it was shown for 2-FTP that the repulsive S–H 1 nσ* state crosses the 1 ππ* state close to its vibrational ground state.

WebMar 19, 2024 · Thiophenols with different substituents were treated with 6.0 equiv of benzyl alcohol at first. The electron-donating group on thiophenols rendered better yields, since methoxy group substituted thiophenol (3e, 72%) gave a better yield than the methyl (3a, 67%; 3b, 50%), fluorine (3d, 60%) or chlorine (3c, 52%) substituted ones. Then, variation ... WebThe concentration of thiophenols compared to volatile phenols in smoke impacted wines is of interest. Volatile phenols are found at much higher concentrations (1-335 µg/L) when compared to thiophenols (< 5 ng/L) in smoke impacted wines (Favell et al., 2024). The grapes are also likely producing higher concentrations of thiophenols than we are ...
