  用于氨基烯烃分子内加氢胺化的栓系双（酰胺）和双（脲）负载的锆预催化剂

  摘要：

  合成了主链中具有中性硫属元素供体（O 或 S）的束缚双（酰胺）和双（脲）前配体，并通过质子分解安装在锆上。双（酰胺）锆配合物采用κ4（N，N，O，O）结合基序，并在具有吡啶供体的固态下进行表征。同样，双（脲）支持的复合物也被发现在固态下具有 κ4(N,N,O,O) 结合基序，但是离散复合物的形成不需要额外的供体配体。对于任何过渡金属物种，都没有发现中性硫属元素供体与锆原子之间相互作用的证据。所有配合物都被筛选为与伯和仲氨基烯烃底物进行分子内加氢胺化反应的预催化剂。有趣的是，

  Constrained Geometry Organoactinides as Versatile Catalysts for the Intramolecular Hydroamination/Cyclization of Primary and Secondary Amines Having Diverse Tethered C−C Unsaturation

  摘要：

  A series of "constrained geometry" organoactinide complexes, (CGC)An(NMe)(2) (CGC = Me2Si(eta(5)-Me4C5)((BuN)-Bu-t); An = Th, 1; U, 2), has been prepared via efficient in situ, two-step protodeamination routes in good yields and high purity. Both 1 and 2 are quantitatively converted to the neutrally charged, solvent-free dichlorides (1-Cl-2, 2-Cl-2) and slightly more soluble diiodides (1-I-2, 2-I-2) with excess Me3Si-X (X = Cl, I) in non-coordinating solvents. The new complexes were characterized by NMR spectroscopy, elemental analysis, and (for 1 and 2) single-crystal X-ray diffraction, revealing substantially increased metal coordinative unsaturation vs the corresponding Me2SiCp ''(2)AnR(2) (Cp '' = eta(5)-Me4C5; An = Th, R = CH2(SiMe3), 3; An = U, R = CH2Ph, 4) and Cp'(2)AnR(2) (Cp' = eta(5)-Me5C5 ; An = Th, R = CH2(SiMe3), 5; An = U, R = CH2(SiMe3), 6) complexes. Complexes 1-6 exhibit broad applicability for the intramolecular hydroamination of diverse C-C unsaturations, including terminal and internal aminoalkenes (primary and secondary amines), aminoalkynes (primary and secondary amines), aminoallenes, and aminodienes. Large turnover frequencies (N-t up to 3000 h(-1)) and high regioselectivities (>= 95%) are observed throughout, along with moderate to high diastereoselectivities (up to 90% trans ring closures). With several noteworthy exceptions, reactivity trends track relative 5f ionic radii and ancillary ligand coordinative unsaturation. Reactivity patterns and activation parameters are consistent with a reaction pathway proceeding via turnover-limiting CC/CC insertion into the An-N sigma-bond.

  N‐heterocyclic carbene (NHC) ligands with naphthyl side chains were employed for the synthesis of unsaturated, yet isolable [(NHC)Ir(cod)]+ (cod=1,5‐cyclooctadiene) complexes. These compounds are stabilised by an interaction of the aromatic wingtip that leads to a sideways tilt of the NHC−Ir bond. Detailed studies show how the tilting of such N‐heterocyclic carbenes affects the electronic shielding

  具有萘基侧链的N-杂环卡宾（NHC）配体用于合成不饱和但可分离的[（NHC）Ir（cod）] +（cod = 1,5-环辛二烯）配合物。这些化合物通过芳族翼尖的相互作用而稳定，从而导致NHC-Ir键的侧向倾斜。详细的研究表明，此类N杂环卡宾的倾斜如何影响卡宾碳原子的电子屏蔽性能，以及13 C NMR信号中的明显高场位移如何反映出这种情况。当用于分子内加氢胺化时，这些[（NHC）Ir（cod）] +在温和的反应条件下，这些物种显示出很高的催化活性。对映体纯的催化剂体系可产生具有出色对映选择性的吡咯烷。

  The combined use of a copper halide, a silver salt and a phosphane ligand was applied for the catalysis of inter- and intramolecular hydroamination of alkenes. The reactions of unactivated olefins with nitrogen substrates were investigated. Mechanistic investigations demonstrated that the catalytic system generated a Brønsted acid which appeared to be the prominent catalytic species.

  Zirconium catalysts sparkle: A new chiral zirconium complex has been used to catalyze hydroamination reactions to cyclize aminopentenes into 2‐methylpyrrolidines (see scheme). The rate law supports a mechanism involving a reversible substrate–catalyst interaction that precedes the rate‐determining step. A new mechanism for zirconium‐catalyzed hydroamination has been proposed based on kinetic isotope

  be used as catalysts for cyclohydroamination of a number of primary and secondary aminoalkenes. The complex [(2,6-iPr2C6H3-BIAN)Zr(NMe2)2(η1-NHMe2)] was isolated and completely characterized, including X-ray diffraction analysis. Despite its easy and almost quantitative isolation, it showed only moderate catalytic performance in the intramolecular hydroamination, irrespective of the cyclization precursor
