摘要

本文介绍了含有单（2-苄基噁唑啉）配体的钯阳离子配合物的合成和表征。我们的研究重点是探索苄基芳香族 π 电子的静电相互作用的影响，旨在增强阳离子钯配合物的结构刚性。引入一个与钯阳离子弱配位的芳香基团后，钯阳离子络合物的稳定性比没有任何配位取代基的络合物提高了两倍。这项研究是 2-苄基恶唑啉阳离子钯配合物的首次实例，突出了弱静电相互作用在阐明金属配合物三维结构方面的重要性。

Enhancing stability of cationic palladium complexes with hemilabile 2-benzyl oxazoline ligands: Structural insights and catalytic implications

This article describes the synthesis and characterization of Pd cationic complexes incorporating mono(2-benzyl oxazoline) ligands. Our study focuses on exploring the impact of electrostatic interactions of aromatic π-electrons of the benzyl group, aimed at enhancing the structural rigidity of cationic Pd complexes. Introduction of an aromatic moiety, which weakly coordinates with the Pd cation, led to a two-fold increase in the stability of the Pd cationic complex compared to complexes lacking any coordinating substituents. This research represents the initial instance of a cationic Pd complex with 2-benzyl oxazolines, highlighting the importance of weak electrostatic interactions in elucidating the three-dimensional structure of a metal complex.

期刊介绍： Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry. Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters. Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
