Isolation and Hydrogenation of a Complex with a Terminal Iridium-Nitrido Bond

摘要

Electron-rich late-transition-metal complexes with terminal metal-nitrogen multiple bonds (M=N, M=N) were considered unstable until only a few years ago. Owing to their postulated existence as transient intermediates in catalytic C-N and H-N bond-formation processes, their synthesis and study remains a highly desirable and challenging target. In this realm, the Haber-Bosch process, for which terminal ruthenium and iron nitrido units are considered active catalytic species, is of special interest.
