Terminal Oxo and Imido Transition‐Metal Complexes of Groups 9–11

Abstract

Abstract This review summarizes the properties of group 9–11 metal–oxo and metal–imido complexes, which have been either isolated or proposed as reactive intermediates in metal‐catalyzed organic transformations. We begin with a general description of the bonding of transition‐metal–oxo and –imido complexes in various geometries, followed by a discussion of complexes from groups 9–11. The focus of this review is to provide a clear picture of the state of the art as well as insight towards potential future synthetic endeavors.
