In this article, the synthesis and characterization of new palladium(η2‐olefin) complexes bearing isocyanides as spectator ligands are described. These derivatives have been tested on olefin exchange reactions, allowing to define a scale of strength of the palladium(0)‐olefin bond. In this way we have proved that dimethyl fumarate can be released by the metal center much more easily than the other olefins and that (Z)‐1,2‐ditosylethene is by far the most firmly anchored to palladium.

测量烯烃与Pd(0)的键强度:涉及烯烃与异氰酸酯配体的钯(0)配合物上的烯烃交换反应的动力学研究,测量烯烃与Pd(0)的键强度:涉及烯烃与异氰酸酯配体的钯(0)配合物上的烯烃交换反应的动力学研究

在本文中,新的钯的合成和表征(η 2烯烃)复合物轴承异氰化物如旁观者配体进行说明。这些衍生物已经在烯烃交换反应中进行了测试,可以确定钯(0)-烯烃键的强度范围。通过这种方式,我们证明了富马酸二甲酯可以比其他烯烃更容易地被金属中心释放,并且(Z)-1,2-二甲苯基乙烯到目前为止是最牢固地固定在钯上的。,在本文中,新的钯的合成和表征(η 2烯烃)复合物轴承异氰化物如旁观者配体进行说明。这些衍生物已经在烯烃交换反应中进行了测试,可以确定钯(0)-烯烃键的强度范围。通过这种方式,我们证明了富马酸二甲酯可以比其他烯烃更容易地被金属中心释放,并且(Z)-1,2-二甲苯基乙烯到目前为止是最牢固地固定在钯上的。
