Synthesis of cyclic polysulfides: Controlled ring-expansion polymerization of cyclic tetrathioester with thiirane

We synthesized cyclic tetrathioesters containing thioester moieties at the o-position (o-CTE) and m-position (m-CTE) of an aromatic skeleton. The reaction of phenoxy propylenesulfide (PPS) with o-CTE and m-CTE was examined using tetrabutylammonium chlorid

Electrochemically Induced Rearrangement of S,S-Diaryl Benzene-1,2-dicarbothioates

The electrochemical reduction of some S,S-diarylbenzene-1,2-dicarbothioates (1) in aprotic medium leads to 3,3-bis(arylthio)phthalides (2) in almost quantitative yield.The reaction is an example of an electrochemically induced chemical reaction.SRN1, in which no external nucleophile is needed and for which the required amount of charge is less than 0.1 F mol-1.
