A novel and efficient three-step protocol for synthesizing functionalized dibenzothiophenes (DBTs) from common starting materials and by using palladium-catalyzed carbon-carbon and carbon-sulfur bond formations is presented. The reaction conditions offer significantly improved functional-group tolerance and regioselectivity as compared to previously reported methods.
