摘要

我们利用耐空气试剂开发了一种模块化、操作实用的 Ni(0)/silane 烯烃异构化系统。该方法的一个吸引人的特点是能够快速筛选各种 N-杂环碳烯 (NHC) 配体,通过对配体骨架进行辅助修饰来优化配体,从而提高反应活性。该系统易于扩展(1 克烯),并能以高 E 选择性容忍各种官能团,包括芳基溴化物、杂环、叔胺和 α,β-不饱和酰胺。初步的机理实验支持 Ni-H 插入/消除途径。

Tuneable, in situ-generated nickel-hydride alkene isomerisation catalyst†

Tuneable, in situ-generated nickel-hydride alkene isomerisation catalyst†
A modular, operationally practical Ni(0)/silane alkene isomerisation system has been developed with air-tolerant reagents. An attractive feature of this method is the ability to rapidly screen a variety of N-heterocyclic carbene (NHC) ligands, enabling optimisation through ancillary ligand backbone modification for enhanced reactivity. This system is readily scalable (>1 g alkene) and tolerates a diverse array of functional groups in high E-selectivity, including aryl bromides, heterocycles, tertiary amines, and α,β-unsaturated amides. Preliminary mechanistic experiments support a Ni–H insertion/elimination pathway.
