Electrochemical oxidations of thioethers: Modulation of oxidation potential using a hydrogen bonding network

Electrochemistry Communications, 2019
A highly efficient chemo-selective electrochemical oxidation of thioethers to sulfoxides and sulfones was developed. The hydrogen bonding network generated from hexafluoro-2-propanol (HFIP) and acetic acid (AcOH) plays an important role in the modulation

Synthesis of New 10-Arylthioanthralins and Oxidation of Thioanthralins to Their Corresponding Sulfones [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1996
Treatment of 10-bromoanthralin (1) with several thiophenols (2) gave the corresponding 10-arylthioanthralins (3) in high yields. Oxidation of thioanthralins (3a-c) and (3k-m) using an excess of m-chloroperbenzoic acid gave the corresponding sulfones (4a ...

Spatial structure of α-halogen-substituted sulfones

, 2020
1. Conformational equilibrium between the gauche- and trans-forms is attained in α-halogenated sulfones with the gauche-form predominating. 2. The position of the aryl radical in α-haloaryl sulfones is close to interfering with.
