Catalytic reactivities of indenyl-nickel, indenyl-palladium, and PCsp3P-nickel complexes

This report describes the catalytic reactivities of a series of Ni and Pd complexes featuring substituted or functionalized indenyl ligands and Ni complexes featuring a PCsp3P type ligand framework. The reactivities of the indenyl complexes encompass styrene homologation (dimerization, trimerization, oligomerization, and polymerization) and hydrosilylation, 1-hexene isomerization, ethylene dimerization and polymerization, phenylacetylene hydrosilylation, coupling reactions of aryl halides with styrene and amines. The reactivities of PCsp3P-Ni complexes is focused on oligomerization of phenylsilane and its addition to styrene, and the addition of aniline to acrylonitrile. The various reactivities discussed herein demonstrate the importance of ligand properties on the catalysis promoted by a given metal.

本报告描述了一系列具有取代或官能化茚基配体的镍和钯配合物以及具有PCsp3P型配体框架的镍配合物的催化反应活性。茚基配合物的反应活性包括苯乙烯同系化（二聚、三聚、低聚和聚合）以及氢化硅烷化、1 - 己烯异构化、乙烯二聚和聚合、苯乙炔氢化硅烷化、芳基卤化物与苯乙烯和胺的偶联反应。PCsp3P - 镍配合物的反应活性主要集中在苯硅烷的低聚及其与苯乙烯的加成，以及苯胺与丙烯腈的加成。本文所讨论的各种反应活性证明了配体性质对特定金属所促进的催化作用的重要性。
