  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

  我们开发了一种有效且直接的方法，通过钯与芳基溴化物催化炔烃的加氢芳基化反应来制备三取代烯烃。二芳基乙炔和烷基（芳基）乙炔可以用各种芳基溴化物以中等至极好的收率很好地进行氢芳基化。机理研究表明，酒精是通过消除β-H来提供氢化物的还原剂。革兰氏反应进一步证明了新开发策略的实用性和有效性。

  A palladium-catalyzed Heck diarylation of terminal olefins under ligand-free conditions in acetic acid is described. This procedure allows double arylation of terminal olefins affording trisubstituted olefins in good to excellent yields. The methodology is applicable to the coupling of both electron-deficient and electron-rich aryl iodides leading to symmetrical and unsymmetrical β,β-diarylated alkenes

  We present an approach to utilize water as the hydride source via Pd(II)/Pd(0) catalysis. As a case study, we have achieved a diboron mediated Pd(II)-catalyzed hydroarylation of alkynes using arylboronic acids. This approach not only complements conventional reactivity of Pd via Pd(0)/Pd(II) cycle for the hydroarylation but also utilizes water as the hydride source. We believe this would particularly

  我们提出一种通过Pd（II）/ Pd（0）催化利用水作为氢化物来源的方法。作为一个案例研究，我们已经实现了使用芳基硼酸的二硼介导的Pd（II）催化炔烃的氢芳基化反应。该方法不仅通过Pd（0）/ Pd（II）循环对Pd的常规反应性进行了补充，还可以利用水作为氢化物源。我们认为，这对于利用水作为试剂特别有益。

  and dioxygen serve as oxidants in highly stereoselective oxidative Pd‐catalyzed Heck arylations in which aryl boronic acids are used to synthesize triarylalkyl‐substituted olefins. The reactions occur under very mild conditions at room temperature. As an example, the threefold sequential arylation of methyl acrylate is the crucial step in the stereoselective synthesis of Z‐Tamoxifen.

  Reaction of symmetrical and unsymmetrical alkynes with arylboronic acids, using PdCl2 as catalyst source and i-Pr2NPPh2 as ligand, afforded trisubstituted alkenes with regioselectivity in good to excellent yields without a common additional acetic acid. Its efficiency has been demonstrated by its good functional groups, high yield and crowded substrates.
