Web18 Sep 2024 · Oxidation of thianthrene S 4 with H 2 O 2 proceeds only in TFA. Contrary to oxidation in MeCN and DCM, cis -SOSO 6a was the major product in reaction in TFA and the selectivity for 6a / 6b was higher at 0 °C. Even after prolonged reaction time at room temperature no sulfone 7 is formed.

Like other 1,4-dithiins but unlike its oxygen analog dibenzodioxin, the shape of thianthrene is not planar. It is bent, with a fold angle of 128° between the two benzo groups. Thianthrene can be prepared by treating benzene with disulfur dichloride in the presence of aluminium chloride. WebTrying to get openVPN to run on Ubuntu 22.10.
