An efficientmethod for sterically demanding Suzuki–Miyauracoupling 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

one-component Pd precatalysts bearing biarylphosphine ligands is described. These precatalysts are air- and thermally stable, are easilyactivated 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. The use of these precatalysts as a convenient source of LPd(0) in C-N cross-coupling reactions
Synthesis of dinuclear palladium complexes having two parallel isocyanide ligands, and their application as catalysts to pyrrole formation from tert-butylisocyanide and alkynes
Novel dinuclear palladium complexes having two isocyanideligands 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.
