Palladium-catalyzed hydroarylation of acetylenes provides regio- and stereodefined olefins. This methodology has been extended to arylpropiolamides where 3,3-diarylacrylamides are prepared stereospecifically. In an independent fashion, both the E- and Z-isomers were prepared by judicious choice of arylpropiolamide preparation and the palladium catalyzed hydroarylation reaction.
