  钯（II）三氟甲基配合物LPd（CF 3）X的一般前体（MeCN）2 Pd（CF 3）OTs的合成

  摘要：

  在钯催化的芳基-三氟甲基交叉偶联反应中，还原消除通常是限速步骤。还原消除的化学计量研究已证明有效地评估了各种配体促进这一具有挑战性的基本步骤的能力。然而，合成钯三氟甲基配合物的困难阻碍了该策略的使用。为了解决这一缺陷，我们在此报告了（MeCN）2 Pd（CF 3）OTs的合成，该化合物是空气和水分稳定的固体，可以用作访问各种LPd（CF 3的常见前体）X复合物。从这种配合物中，我们能够制备带有许多单膦，双膦和二胺配体的三氟甲基钯配合物，这些配体已知有助于促进Ar–CF 3和乙烯基–CF 3的还原消除。此外，我们发现通过修饰所用的NaX或AgX盐可以容易地改变阴离子配体（X）。

• An Efficient Method for Sterically Demanding Suzuki-Miyaura Coupling Reactions
  作者：Qing Zhao、Chengxi Li、Chris H. Senanayake、Wenjun Tang

  日期：2013.2.11

  An efficient method for sterically demanding Suzuki–Miyaura coupling reactions has been developed with two catalysts, Pd/BI‐DIME (see scheme) and Pd/phenanthrene‐based ligand. The Pd/BI‐DIME catalyst facilitates the syntheses of extremely hindered biaryls bearing ortho‐isopropyl substituents. The other catalyst is efficient for the synthesis of functionalized tetra‐ortho‐substituted biaryls at low

  which shows a Pd(II) metal, a DPPF ligand, and two CF3COO ligands. TwoCp rings in theDPPF ligand are not perfectly parallel,with a dihedral angle of 4.4(4) . ThePd Fe separation of 4.1932(8)A indicates no direct interactions between these two metals. We examined the ligand exchange reaction of complex 8 with 2 equiv of NaN3 in CH2Cl2 (Scheme 2). The reaction readily proceeded to give a Pd(II) azide complex

  羧酸盐通过它们的氧原子以末端、螯合或桥接的方式与过渡金属配位，并在各种催化反应中充当活性配体。众所周知，具有三氟乙酸盐 (TFA) 配体的过渡金属配合物比相应的乙酸盐对应物具有更高的溶解度和结晶度，具体取决于金属的特性。特别是，后过渡金属的 TFA 配合物是多种有机反应的有效催化剂，包括异氰化物或丁二烯的聚合以及 CO 和烯烃的共聚。此外，在有机底物的有氧氧化、乙烯基转移形成烯酰胺或在 Pd 催化剂存在下有机底物的氧化环化方面，这种配合物比相应的醋酸盐配合物表现出更高的效率。尽管已经报道了许多催化 Suzuki-Miyaura CC 偶联反应，但涉及后过渡金属-TFA 配合物的反应仍然很少见。出于这个原因，我们试图开发一种新的合成途径来合成具有螯合膦配体的 Pd-TFA 配合物，以用于这种偶联反应。在这项工作中，我们制备了一系列 Pd(II)-TFA-（螯合二膦）配合物，并研究了芳基卤化物和芳基硼​​酸的催化

These precatalysts are air- and thermally stable, are easily activated under normal reaction conditions at or below room temperature, and ensure the formation of the highly active monoligated Pd(0) complex necessary for oxidative addition.

  Novel dinuclear palladium complexes having two isocyanide ligands were synthesized by using a binucleating ligand, N,N′-bis[2-(diphenylphsphino)phenyl]formamidinate (dpfam). The structure of [Pd2(μ-dpfam)(tert-BuNC)2]Cl was confirmed by X-ray analysis, showing that the Pd–Pd bond length of 2.5824(3) Å falls well within the range of those for known dipalladium complexes having the edge-sharing structure

• Opposite influence of calf thymus DNA on the rate of substitution of ethylenediamine, by thiourea, in the complex cations [Pd(bpy)(en)]2+ and [Pd(bromazepam)(en)]2+ (bromazepam = 7-bromo-1,3-dihydro-5-(2-pyridyl)-2H-1,4-benzodiazepin-2-one)

  Calf thymus DNA inhibits the substitution of ethylenediamine, by thiourea, in [Pd(bpy)(en)]2+ and catalyses the same reaction in [Pd(bromazepam)(en)]2+ (bromazepam = 7-bromo-1,3-dihydro-5-(2-pyridyl)-2H-1,4-benzodiazepin-2-one); this kinetic effect can be related to the different binding modes of the two complexes to the biopolymer.
