Abstract
Electrochemical synthesis of dibenzothiophene derivatives was achieved. Several bis(biaryl) disulfides are efficiently converted to dibenzothiophenes by electrochemical oxidation. The use of BuNBr as a halogen mediator was essential, and wide varieties of dibenzothiophene derivatives were obtained in good yields.
