    摘要:
    一个直接的和新的N-杂环卡宾(NHC的)可扩展的八步合成已经从便宜和容易获得2-硝基开发米二甲苯。该过程可以制备一类新的NHC,即ITent(称为“帐篷”的“帐篷”),其中著名的IMes(N,N′-双(2,4,6-三甲基苯基)咪唑-2-亚烷基),IPr(N,N'-双(2,6-二(2-丙基)苯基)咪唑-2-亚基)和IPent(N,N'-双(2,6-二(3-戊基)苯基)咪唑-2-亚基NHC是最简单且已知的同类物。该合成路线已成功用于准备ITent系列的三个成员:IPent(N,N′-双(2,6-二(3-戊基)苯基)咪唑-2-亚基),IHept(N,N′-双(2,6-二(4-庚基)苯基)咪唑-2-亚基)和INon(N,N'-双(2,6-二(5-壬基)苯基)咪唑-2-亚基)。通过制备镍和钯配合物,研究了每种NHC的电子和空间特性。最后,研究了这些新的ITent配体在Pd催化的Suzuki-Miya

    Buchwald–Hartwig cross-coupling reactions of sterically demanding aryl chlorides with sterically hindered and deactivated aniline derivatives. This catalyst also proved efficient in Suzuki–Miyaura reactions, thus allowing the preparation of tetra-ortho-substituted biaryls. The Kumada–Corriu coupling has also been investigated using this palladium N-heterocyclic carbene (NHC) catalyst.

    Into the groove: The introduction of a C2‐symmetric N‐heterocyclic carbene ligand with appropriately substituted naphthyl side chains enables the efficient Suzuki–Miyaura coupling to form bulky tetra‐ortho‐substituted biaryls from aryl bromides and chlorides at room temperature. DFT calculations uncover the subtle steric phenomena at play that lead to the superior catalytic performance. Cyoct=cyclooctyl

  • Design of a Versatile and Improved Precatalyst Scaffold for Palladium-Catalyzed Cross-Coupling: (η<sup>3</sup>-1-<sup>t</sup>Bu-indenyl)<sub>2</sub>(μ-Cl)<sub>2</sub>Pd<sub>2</sub>
    作者:Patrick R. Melvin、Ainara Nova、David Balcells、Wei Dai、Nilay Hazari、Damian P. Hruszkewycz、Hemali P. Shah、Matthew T. Tudge

    We describe the development of (eta(3)-1-Bu-t-indenyl)(2)(mu-Cl)(2)Pd-2, a versatile precatalyst scaffold for Pd-catalyzed cross-coupling. Our new system is more active than commercially available (eta(3)-cinnamyl)(2)(mu-Cl)(2)Pd-2 and is compatible with a range of NHC and phosphine ligands. Precatalysts of the type (eta(3)-1-Bu-t-indenyl)Pd(Cl)(L) can either be isolated through the reaction of (eta(3)-1-Bu-t-indenyl)(2)(mu-Cl)(2)Pd-2 with the appropriate ligand or generated in situ, which offers advantages for ligand screening. We show that the (eta(3)-1-Bu-t-indenyl)(2)(mu-Cl)(2)Pd-2 scaffold generates highly active systems for a number of challenging cross-coupling reactions. The reason for the improved catalytic activity of systems generated from the (eta(3)-1-Bu-t-indenyl)(2)(mu-Cl)(2)Pd-2 scaffold compared to (eta(3)-cinnamyl)(2)(mu-Cl)(2)Pd-2 is that inactive Pd-I dimers are not formed during catalysis.
