代谢
钯可能通过口服、皮肤接触和吸入暴露而被吸收。一旦进入体内,它会分布到肾脏、肝脏、脾脏、淋巴结、肾上腺、肺和骨骼中。钯能够形成配合物的能力使它能够与氨基酸、蛋白质、DNA和其他大分子结合。钯及其代谢物通过尿液和粪便排出体外。(A21)
Palladium may be absorbed through oral, dermal, and inhalation exposure. Once in the body it distributes to the kidney, liver, spleen, lymph nodes, adrenal gland, lung and bone. Palladium's ability to form complexes allows it the bind to amino acids, proteins, DNA, and other macromolecules. Palladium and its metabolites are excreted in the urine and faeces. (A21)

毒理性
  • 毒性总结
由于钯离子能够与无机和有机配体形成稳定的络合物,它们可以干扰细胞平衡,取代其他必需离子,并与大分子如蛋白质或DNA的功能团发生相互作用。与DNA和RNA结合的钯络合物会导致链断裂。钯离子能够抑制大多数主要的细胞功能,包括DNA和RNA的合成。钯化合物已被证明能够结合并抑制多种酶,包括肌酸激酶和脯氨酸羟化酶。
Due to their ability to form strong complexes with both inorganic and organic ligands, palladium ions can disturb cellular equilibria, replace other essential ions, and interact with functional groups of macromolecules, such as proteins or DNA. Palladium complexes binding to DNA and RNA leads to strand breakage. Palladium ions are able to inhibit most major cellular functions, including DNA and RNA synthesis. Palladium compounds have been shown to bind to and inhibit various enzymes, including creatine kinase and prolyl hydroxylase. (L798)

制备方法与用途

化学性质

双(二亚芐基丙酮)钯(Pd(dba)₂)通常是一种黑色或浅棕色的粉末固体。它是一种空气稳定的零价钯复合物,作为有效的过渡金属催化剂,在多种有机反应中表现出色,如交叉偶联反应、氢化反应和偶极环加成反应等。在有机合成过程中,以双(二亚芐基丙酮)钯为催化剂的反应通常具有高效性、高选择性和良好的功能性团容忍度。

结构特性

双(二亚芐基丙酮)钯的结构中,二亚苄基丙酮通过C=C双键与零价钯形成π键配位。分子内部没有Pd-Cσ键的形成,配合物的稳定性主要归因于σ配键和反馈π配键的协同作用以及多齿配位因素的影响。合成零价钯的二亚苄基丙酮配合物的关键在于控制反应温度,并且与反应体系的pH值、避氧措施等因素密切相关。

用途

双(二亚芐基丙酮)钯不仅可用作电位计膜传感器组件中的化合物,能够选择性地检测吸烟者尿液中硫氰酸盐的存在,还可作为由二环戊二烯合成三环戊二烯的均相催化剂之一。此外,在Suzuki、Kumada和Negishi等偶联反应中,双(二亚芐基丙酮)钯也被用作高效的催化剂。

    Stereoelectronic Control on the Kinetic Stability of β-Acetoxy-Substituted (η3-Allyl)palladium Complexes in a Mild Acidic Medium
    摘要:
    Deuteromethanolysis of trans-and cis-beta-acetoxy-substituted (eta(3)-cyclohexylallyl)palladium complexes (1 and 2) were studied under mild acidic conditions. The trans-beta-acetoxysubstituted complex (1) reacted about 200 times faster than its cis-substituted counterpart (2). A theoretical analysis of the structure and stability of slightly simplified model compounds (4-7) was performed employing density functional theory at the B3PW91 level in order to elucidate the relationship between the rate of deuteromethanolysis and the electronic interactions between the beta-acetoxy substituent and the palladium atom. In the traits complex, the stereoelectronic requirements of the conjugative interactions between the palladium atom and the C-O(Ac) bond are fulfilled, which facilitates the C-O(Ac) bond cleavage in the deuteromethanolysis reaction. Since the substituent geometry in the cis complex is different, these conjugative interactions are suppressed, providing a greater kinetic stability for the cis complex under the reaction conditions applied. Since the (eta(3)-allyl)palladium complexes studied and their derivatives are key intermediates of important palladium catalyzed transformations, the implications of the beta-substituent effects for the regio-and chemoselectivity of the nucleophilic attack have also been discussed.
