摘要

Krossing等人报道了一种在溶液和固体状态下合成和表征阳离子[Mn(CO)5（正戊烷）]+配合物的新方法。优雅的策略显著提高了室温下σ-戊烷配合物在溶液中的寿命，并允许在0℃下结晶。这篇新闻文章总结了各种表征方法（核磁共振、x射线）的发展。最值得注意的是，Krossing和他的同事最近发现了一条途径，将正戊烷碳氢键连接到一个高度缺电子的阳离子锰(I)羰基中心。

A new recipe for the isolation of a cationic Mn-pentane σ-complex

Krossing et al. reported a new method for the synthesis and characterization of a cationic [Mn(CO)₅(n-pentane)]⁺ complex in both solution and solid state. The elegant strategy significantly improved the lifetime of the σ-pentane complex in solution at room temperature and allowed crystallization at 0 °C.

Graphical abstract

This news story article summarizes the development of various strategies for the characterization (NMR, X-ray) of sigma-alkane complexes. Most notably, a recently discovered route by Krossing and coworkers to make a n-pentane C-H bond ligated onto a highly electron-deficient cationic manganese(I) carbonyl centre is highlighted.

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
