摘要

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.
