摘要

本文首次介绍了氯铂络合物在碱存在下与丙酮反应生成丙酮基三叉 CˆNˆN 芳基联吡啶络合物的实例。通过 1H、13C NMR、COSY、HSQC 和 HMBC 技术确定了所获物质的化学结构。通过一维和二维核磁共振实验，对合成的乙酰基环铂络合物的核磁共振光谱中的所有质子和碳信号进行了归因。对同阶 C-Pt 自旋-自旋耦合常数的值进行了比较分析，结果表明芳基联吡啶配体环状片段的键长和价角存在显著差异。

Acetonyl C^N^N platinum(II) complexes of arylbipyridines

This paper presents the first example of the formation of acetonyl tridentate CˆNˆN complexes of arylbipyridines in the reaction of chloroplatinum complexes with acetone in the presence of alkali. The chemical structure of obtained substances was established by means of ¹H,¹³C NMR, COSY, HSQC, and HMBC techniques. The attribution of all proton and carbon signals in NMR spectra was performed using 1D and 2D NMR experiments for the synthesized acetonyl cycloplatinated complexes. A comparative analysis of the values of the C-Pt spin-spin coupling constants of the same order was carried out, which showed a significant difference in bond lengths and valence angles inthe cyclic fragments of the arylbipyridine ligand.

期刊介绍： MRC is devoted to the rapid publication of papers which are concerned with the development of magnetic resonance techniques, or in which the application of such techniques plays a pivotal part. Contributions from scientists working in all areas of NMR, ESR and NQR are invited, and papers describing applications in all branches of chemistry, structural biology and materials chemistry are published. The journal is of particular interest not only to scientists working in academic research, but also those working in commercial organisations who need to keep up-to-date with the latest practical applications of magnetic resonance techniques.
