An efficient and practical synthetic method has been developed for the preparation of symmetrical diarylacetylenes from the direct reaction of aryl chlorides with 2-methyl-3-butyn-2-ol catalyzed by palladium(II) chloride-bis(tricyclohexylphosphine) [PdCl2(PCy3) 2] under mild reaction conditions. Unsymmetrical diarylated acetylenes could be also obtained by using two different aryl chlorides simultaneously. The catalytic procedure includes a novel one-pot palladium-catalyzed, double Sonogashira coupling of inactivated aryl chlorides without use of copper(1) as co-catalyst.

Pd/CuFe2O4 nanowire-catalyzed cross coupling transformations are described. Notably, these reactions showed excellent functional group tolerance. Further, the protocol is applied to a one-pot synthesis of benzofurans via a Sonogashira coupling and intramolecular etherification sequence. The catalyst was reused and found to maintain its activity and stability.
