Abstract

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.

闪光通讯：3-碘吡啶在二膦镍配合物上的氧化加成：探测次生硼烷效应

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。

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
