摘要
n -杂芳基亲电试剂的催化交叉偶联是获得功能化环体系的有力策略。本研究探讨了[Ni(二膦)]配合物与3-碘吡啶的反应性。当二膦配体具有悬垂的硼烷部分时,发生氧化加成,导致形成具有负性B-N相互作用的稳定二聚体{Ni}2。这些发现与含有正烷基的配体类似物对比,突出了次级配位球效应。
Flash Communication: Oxidative Addition of 3-Iodopyridine at a Nickel Diphosphine Complex: Probing Secondary Borane Effects
The catalytic cross coupling of N-heteroaryl electrophiles is a powerful strategy for accessing functionalized ring systems. This study explores the reactivity of [Ni(diphosphine)] complexes with 3-iodopyridine. When the diphosphine ligand features a pendent borane moiety, oxidative addition occurs, leading to the formation of a stable dimeric {Ni}2 species having dative B–N interactions. These findings are contrasted against an n-alkyl containing ligand analogue, highlighting a secondary coordination sphere effect.
