Sixteen-electron Ni(0) complexes bearing trans-stilbene derivative ligands have been shown to display a high degree of stability toward oxidation in the solid state. A structural analysis of a unique family of tris Ni(0) stilbene complexes revealed a remarkable effect of the steric hindrance of the substituents at the para position of the stilbene unit to temperature, oxidation, and degradation in solution. From these analyses, Ni(4-tBustb)3 arose as a long-term air-, bench-. and temperature-stable Ni(0) complex. Importantly, Ni(4-tBustb)3 presents faster kinetic profiles and a broader scope as a Ni(0) source, thus outperforming the previously described Ni(4-CF3stb)3 in a variety of relevant Ni-catalyzed transformations.

Ni(4-tBu stb)3:用于催化的坚固的16电子Ni(0)烯烃配合物

带有反式二苯乙烯衍生物配体的十六电子Ni(0)配合物已显示出对固态氧化具有很高的稳定性。三的Ni(0)配合物茋的独特家族的结构分析揭示了取代基的空间位阻在一个显着的效果二苯乙烯单元的温度,氧化和退化在溶液中的位置。根据这些分析,Ni(4-tBu stb)3作为长期的空气,实验台出现。和温度稳定的Ni(0)配合物。重要的是,Ni(4-tBu stb)3作为Ni(0)源具有更快的动力学曲线和更广阔的范围,因此优于先前描述的Ni(4-CF3)stb)3在各种相关的Ni催化转化中。
