  Investigation of Steric and Electronic Features of 3-Iminophosphine-Based Palladium Catalysts for Intermolecular Hydroamination

  摘要：

  A series of (3-iminophosphine)allylpalladium triflate complexes with systematic variation of both steric and electronic features was isolated and characterized. The ability of the complexes in this series to catalyze the regioselective hydroamination of 3-methyl-1,2-butadiene with aryl amines to form solely the kinetic product was probed by observing conversion to products via NMR spectroscopy. The previously unstudied 3-iminophosphine ligand composed of a di-tert-butyl phosphine, cyclobutene backbone, and tert-butyl imine provided the most active palladium hydroamination catalyst for this transformation known to date.

• Cationic Nickel(II)-Catalyzed Hydrosilylation of Alkenes: Role of P, N-Type Ligand Scaffold on Selectivity and Reactivity
  作者：Istiak Hossain、Joseph A. R. Schmidt

  Seven structurally similar cationic nickel(II)–alkyl complexes were synthesized by using a series of P, N ligands, and their reactivity was explored in the hydrosilylation of alkenes. More electron-rich phosphines enhanced the overall reactivity of the transformation; in contrast, groups on the imine donor had little impact. Overall, these catalysts displayed reactivity and selectivity that was previously

  使用一系列P，N配体合成了七个结构相似的阳离子镍（II）-烷基络合物，并在烯烃的氢硅烷化中探索了它们的反应性。更多的富电子膦提高了转化的整体反应性；相反，亚胺供体上的组几乎没有影响。总体而言，这些催化剂显示出在镍催化的氢化硅烷化中以前未知或非常罕见的反应性和选择性。在与Ph 2 SiH 2的反应中，1,2-二取代的乙烯基芳烃显示出对硅烷加成的完全苄基选择性，而对1,1-二取代的烯烃则观察到末端选择性。相关的PhSiH 3导致仅对单个取代的乙烯基芳烃进行马尔可夫尼科夫选择性，而未观察到竞争的双加成。机理研究支持以下假设：Ni-H在此催化氢硅烷化反应中充当活性物质，这反过来也显示了硅烷再分布反应的催化能力，特别是对于空间不受阻的硅烷。

  The first example of nickel‐catalyzed hydroamination of allenes is reported. The new cationic [(3‐iminophosphine)nickel(allyl)]+ catalysts have been fully characterized and act regioselectively in the catalytic hydroamination of allenes with secondary amines at room temperature.
