title: One-pot synthesis of diarylalkynes using palladium-catalyzed sonogashira reaction and decarboxylative coupling of sp carbon and sp2 carbon.
abstract: Decarboxylative coupling of sp-sp2 carbons is possible by palladium catalyst. Employing propiolic acid (1) as a difunctional alkyne, and using the consecutive reactions of the Sonogashira reaction and the decarboxylative coupling, unsymmetrically substituted diaryl alkynes were obtained in moderate to good yield.
