Although transient and difficult to observe, well-defined σ-alkane complexes are now becoming established due to the developments in characterization techniques alongside synthetic methodologies that allow for their observation. Although the number of such complexes still remains relatively small compared to other σ-complexes, such as those with dihydrogen, their growing number and diversity promises much for the future in terms of the development of their fundamental structure and bonding and their role in selective C–H bond activation and functionalization. In this perspective review, the synthesis and characterization of σ-alkane complexes are presented, and the onward reactivity of relatively well-defined examples discussed, with the emphasis on recent results. |
