We developed an efficient and straightforward method to prepare tri-substituted alkenes through palladium-catalyzed hydroarylation of alkynes with aryl bromides. Diarylacetylenes and alkyl(aryl)acetylenes could be well hydroarylated with various aryl bromides in moderate to excellent yields. Mechanistic studies suggested that alcohol was the reductant to provide hydride through β-H elimination. Gram scale reaction further demonstrated the practicality and efficiency of the newly developed strategy. (Figure presented.).
