Abstract
An electrochemical approach toward rearrangement of O-aryl thiocarbamates to S-aryl thiocarbamates at room temperature requires only catalytic amounts of electric charge. The electrolysis can be carried out with the simple equipment under galvanostatic conditions in an undivided cell. In a microflow reactor, almost quantitative yields can be achieved without using a supporting electrolyte.
