Conditions for a FeCl3/PPh3-catalyzed and palladium-, copper-, amine free-Sonogashira coupling reaction of aryl halides with terminal alkynes are reported. The protocol was applicable to a wide variety of substituted aryl iodides and alkynes with different steric and electronic properties and gave excellent yields of the desired coupling products.

An efficient and general protocol for the deacetonative Sonogashira coupling of aryl propargyl alcohols with aryl chlorides is described. The reaction proceeded smoothly with the catalyst system of palladacycle/Xphos. This result represents the first successful deacetonative Sonogashira version for electron-poor, electron-neutral, and even inactive sterically hindered electron-rich aryl chlorides.

Iodination of activated arenes by air-oxidation is carried out in the presence of catalytic bismuth salts at room temperature. Subsequently, the formed iodoarenes react with terminal alkynes to give arylalkynes under a selected palladium-catalyzed coupling condition in the same pot.
