Arylation : Palladium‐catalyzed arylation of ortho ‐sulfanyl aryl halides with sodium tetraarylborates proceeds smoothly without any additional bases in high yields, providing a reliable route to 2‐sulfanylbiaryls. This protocol offers a practical solution to overcome the poisoning behavior of aryl sulfides with palladium species. The conditions worked well with various halides and functional groups. This strategy provides a short and efficient route to dibenzothiophenes through Pummerer‐type cyclization.
