A palladium-catalyzeddesulfitative hydroarylation of alkynes with arylsulfinicacid sodium salts is described. The reaction showed good regio- and stereoselectivity, and afforded the hydroarylation products in good yields. Various functional groups were well tolerated under the optimized reaction conditions.

A directing group‐free, ligand‐promoted palladium‐catalyzed C−H arylation of internal alkynes with simple arenes was developed. Alkenyl chlorides resulting from a 1,4‐chlorine migration or trisubstituted alkenes were produced in moderate to good yields depending on the type of alkyne.
