Abstract
Purpose of this review is to provide an overview of the results obtained since 1995 in the chemistry of tri‐valent uranium. The three main aspects of the reactivity used to cover and organize the literature data are:
Molecular Activation. The reactivity of trivalent uranium complexes is reviewed in terms of ability to interact with both inert and less inert functions (sp

C‐H bond, N

and H

O) by emphasizing the variety of transformations and the unusual bonding features.
Coordination Chemistry. The coordination chemistry of trivalent uranium is comprehensively reviewed by focusing on compounds featuring C‐, N‐, S‐, and O‐donor based ligand complexes.
Divalent Synthetic Equivalents. The ambiguity of these fascinating species, displaying a formal appearance of divalent complexes but having in reality electronic structures of tri‐ or higher valent species, is reviewed in the light of their ability to perform transformations as could be expected for genuine divalent species.
