Titanium and vanadium imido-bridged complexes

•Survey of the synthesis of Ti- and V-complexes with bridging imido ligands.•Structural properties of μ-NR complexes of Ti and V.•Applications.

This review summarizes the syntheses, structures, reactivity, and applications of titanium- and vanadium-complexes bearing a bridging imide group reported until September 2014. The incorporation of this functional group has evolved from ‘fortuitous approaches’ to designed syntheses of molecules of higher diversity and greater complexity. The review begins with an introduction and a general and brief description of the bridging imido motifs, followed by a discussion of the more common synthetic approaches used to generate such Ti and V compounds. The main focus of the review is the survey of the imido-bridged complexes of Ti and V with an emphasis on their synthesis and reactivity, and with a particular attention to the recent research conducted in the author's group at the Laboratoire de Chimie de Coordination (LCC), as this review is part of a thematic issue “Perspective in coordination chemistry on the occasion of the 40th anniversary of the LCC-CNRS”.
